Good Morning and happy Friday!!
How many different species of plants and animals are there in the world and where are the majority of them found?
How do researches determine where new organisms are placed in taxonomy?
Which ecosystem is considered to have the greatest biodiversity?
From the research i did i found out that there are 1.5 million different species types of plants and animals. They can determine where they are placed by their DNA and their appearance. I found that the greatest biodiversity is in the world is in the rainforest.
ReplyDeleteThere are at least 12,000 species of plants and at least 1,250,000 species of animals currently discovered but there are still some undiscovered.
ReplyDeleteThe researchers study their data and other scientist's data and if the organism does not belong to a taxon then the researcher places them in their own taxon.
Tropical rain forests have been found to have the most biodiversity of all the ecosystems on Earth.
1.) What's so good about it?
ReplyDelete2.) Currently there are about 1.4 million species described. Yet, we're probably far from being close to the actual number of species.
3.) "I did not find those things in the chinese Google..." But really, I didn't find any info on this.
4.)The tropical rainforest has the greatest biodiversity. It has hundreds of thousands of species of beetle.
This is a very difficult questions because no one knows for sure, So far, Zoologists have recorded 20,000 species of fish, 9,000 species of birds, 1,000 species of amphibians, and 15,000 species of mammals. There are about 375,000 species of plants. Rainforests have the most plants and Animals.
ReplyDeleteResearchers determine where animals are classified by the series of steps in the classification system. They check to see what they have in common with other animals and what classifications in the series they fall under.
The ecosystem with the greatest biodiversity is forests, especially tropical rain forests. They support life for many species because of their warmth, water, and vegetation.
Up to 100 million species may be existent on Earth, and only about 20-30 million species have been discovered. The majority are found in rainforests such as the Amazon Rainforest. 40-70% of the world's species exist in the rainforests, and most have not even been discovered. The scientists organize organisms into groups by their evolutionary tree, where species close to one another would be closely related, and farther species would be distantly related. The tropical ecosystems and biomes such as rainforests and other humid and moist areas like the Cape Florestic Province have the greatest biodiversity because the temperatures and conditions allow for there to be more varied species that have adapted and evolved.

ReplyDeleteIt is not certain as to how many species are in the world, but it is estimated that there are about 1.8 million species found and plenty more still not discovered. The Animal Kingdom alone discovers about 15,000-20,000 new species every year. No one has seen the entire world from coast to coast because people have studied sections and I would say the area with the most animals would probably have to be the ocean because there are to many animals in the ocean and I bet have of them are not even discovered yet.
ReplyDeleteResearchers have found many new species and there have been many ways to classify them. If they have found a new species, then they have to figure out a classification for that species. If there data does not show any information about the animal, then it is put into its own group.
The place with the most biodiversity is the rainforest because it has a widespread variety of plants and animals. This a a good spot for plants and animals to live because it is moist, warm and it is generally safe.
"The National Science Foundation’s “Tree of Life” project estimates that there could be anywhere from 5 million to 100 million species on the planet, but science has only identified about 2 million."
ReplyDeleteMost species are found in areas with a great deal of biodiversity, (e.g. the rainforest).
Organization of species in taxonomy is determined through binomial nomenclature. Species are filed into various subsections by criteria considered most relevant and unique to them. As a quick example, an animal is mammal if it breathes air, has three bones in the inner ear, and the males have fur.
The rainforest is generally considered to be the most biodiverse area on the planet.
1. Knowing how many species there are in the world is very hard to specify or even estimate, but right now there are about 1.4 species specified. Scientist know that this is very far off from the actual number, which is estimated between 10 and 13 million, since there are probably millions of species not specified yet.
ReplyDelete2. Classification of new organisms is very involved. Scientists and researchers must identify, name, and group the organism into a formal system based on similarities, physical functions, genetic makeup, and history.
3. Smithsonian scientists say that tropical rain forests have the greatest biodiversity over Amazonia. They have identified, tagged, and measured more than 50,000 individual trees before coming to the conclusion that the tropical rain forests represents the quintessence of biodiversity.
There is an estimated amount of about 1.5 million animals and about 14,000 plants on this planet. They are mostly located in rain forests around the world.
ReplyDeleteIt all depends on the DNA of the organisms or what it's appearance is. Taxonomy is the scientific classification of things.
The ecosystem that is considered to have the greatest biodiversity is the ocean.

ReplyDeleteThere may be an indefinite number of different species in the world, but we have discovered only about 2 million. There are around 2,000 known plant-eating bug species in North America according an AMNH entomologist. In Australia there are about 3,000. There are certain "hotspots" where many species are found such as the northern area of North America and southwest Pacific islands.
ReplyDeleteResearchers determine where new organisms are placed in taxonomy by categorizing them by importance, Latin name, Kingdom, Phylum
Class, Order, Family, Genus, and Species.
The ecosystems thought to contain the greatest biodiversity are tropical rain forests such as Panama and Amazonia. ALthough, smithsonian scientists say that the question really depends on the size and scale of the ecosystem.
1. There are is an upward of 1,594,000 species of plants and animals out of over 50 million on the Earth. The majority of these organisms are found in places around the world where there are plenty of resources for the animals or plants to survive such as rain forests or coral reefs as well as grasslands.
ReplyDelete2. Often times researchers will use a Taxonomic Key to classify animals. A taxonomic key is a bunch of different steps to identifying an organism.
3. The Amazonian ecosystem is said to have the greatest biodiversity and the richest environment.
There is about 1.5- 2 million different species on the earth, and that includes plants, animals, and bacteria. There are many animals and plants on the earth that still haven't been discovered, like ones that live on the bottom of the ocean. Most of them are found in tropical rain forests. I figured out that rain forests have the most biodiversity out of any other kind of habitat on the earth. Rainforest are home to animals like caterpillars and spider monkeys even toucans. Scientists classify animals by their DNA and what they have in common with other animals.
ReplyDeleteMSNBC saids that there is an estimate of between 5 million to 100 million species on Earth, but we have only discovered approximately 2 million of them. The National Science Foundation's "Tree of Life" project uncovered these results. We have only discovered only 10% of all living organisms on Earth. The place in the world where the majority of them are found is the rainforest. Rainforests are home to half of all the living animal and plant species on the planet.
ReplyDeleteScientists go by a classification system to identify the organism. They see the similarities and differences to other, already classified species. They look at the behavior and characteristics of the newly discovered organism. Once they do this, then they can place them on the biological classification. The biological classification is Life, domain, kingdom, phylum, class, order, family, genus, and species. The classification can vary between active organisms and vegetation.
The ecosystem that is considered to have to greatest biodiversity is the tropical rainforest. They have to richest ecosystem on Earth. Rainforest house many of Earth's species. And there is still many to be discovered.
*1. ...out of over 50 million organisms on the Earth.
ReplyDeleteIt is unknown how many organisms are in the world because not all of the, have been discovered yet. There are also many varied estimates, and one of them is from 5 million to 100 million. Only 2 million have been officially discover by science, but new species are found very frequently. The majority of the species found are discovered in the rainforest.
ReplyDeleteScientists place organisms in taxonomy by looking at their relationships with other (already classified) animals and by what type of animal they are (mammal, reptile,...)
The ecosystem that is considered to have the greatest biodiversity is The rainforest because it has so many different organisms that create symbiosis and compete for resources.

It is estimated that there are around five million to one hundred million species that exist on Earth. Of these species, only 2 million have been discovered. A majority of these species are insects, bacteria, and other small microbes that live in the ocean. “We’ve only touched the surface of understanding animal life,” said entomologist Brian Fisher of the California Academy of Sciences.

Scientists determine where new organisms are placed in taxonomy by their genotypic type (genetic type) or their phenotypic characteristics (physical characteristics). Without this science, we would not know things like how humans are closely related to apes. Taxonomy also helps scientists determine the process through which organisms evolved throughout history. With all the undiscovered species in the world, taxonomy is still a work in progress.

The Amazon rainforest is considered to have the greatest biodiversity of all ecosystems. The ecosystem is so complex that scientists are having trouble creating models representing this ecosystem.

Nobody knows exactly how many animals there are, but zoologists have estimated there to be 20,000 species of fish, 6,000 species of reptiles, 9,000 species of birds, 1,000 species of amphibians, and 15,000 species of mammals. Although there are over 1,000,000 species of insects discovered, there're could be over 1,000,000 more undiscovered. The majority of animals are found in rain forests. There are over 375,000 species of plants, including seed plants, bryophytes, ferns, and fern allies, which are relatives of ferns. The majority of plants are in wet, damp places. Taxonomists classify organisms into groups called species, genus, family, order, class, phylum, and kingdom. To organize the species, they study specimens that they have collected or have been collected by another person or museum, then they record the data and study data from other researchers. Using statistical methods, taxonomists classify animals. Scientists predict that forests, usually tropical, have the greatest biodiversity.
ReplyDeleteCurrently there are around 1556 known species of plants and animals. The majority of marine animals are found on or near coral reefs. I could not find where the majority of ALL organisms live, but I'm guessing in the ocean because the Earth is 70% water and only 30% is land. Researchers who classify where new organisms are placed in taxonomy are called Taxonomists. They determine where new organisms go by their physical or cellular characteristics. These scientists also try to determine the evolutionary relationships among these organisms. When a new organism is discovered, whether it is a plant, animal, or a microorganism, a taxonomist will give it a Linnaean designation. That is, he or she will put it in the appropriate categories within the taxonomic levels of kingdom, phylum, class, order, family, genus, and species. Tropical rain forests have the greatest biodiversity of all ecosystems. Although they cover less than 2 percent of Earth's surface, they house an estimated 50% of all life on the planet. The immense numbers of creatures that inhabit the tropical Rainforests are so great- an estimated 5-50 million species- they are almost incomprehensible. For example, whereas temperate forests are often dominated by a half dozen tree species or fewer that make up 90% of the trees in the forest, a tropical rainforest may have more than 480 tree species in a single hectare.

According to a current results, there are 321,212 species of plants, 62,305 vertebrate animals, and 1,305,250 invertebrate animals on planet Earth, not including single-celled bacteria or domestic animals. The Easter Arc Mountains are a biodiversity hotspot for plants with over 1,100 endemic plant species. The Eastern Afromontane is contains a variety of animal species, as well as the Albertine Rift.
ReplyDeleteTaxonomists classify organisms on 7 different levels: life, domain, kingdom, phylum, class, order, family, genus, and species. Basically, they are categorized based on their degree of relatedness with the others being examined, similar to the workings of beta-diversity.
The ecosystem with the greatest quantity of biodiversity is considered to be the tropical rainforest. This is true because of the variety and interdependence rate. Animals and plants depend on each other with mutualistic, parasitic, and commensalistic relationships. The forest provides great shelter and lifestyles for animals.
I meant around 1,556,000 species
ReplyDeleteThere are 7,227,130 different species in the worldl. 80,500 of which are vertebraes. 6,755,830 of the total are invertebraes. 390,800 are plants. These results don't include domestic animals such as sheep, goats, or camels. The Amazon ecosystem is the richest of biodiversity it is also the place where the majority of the species are found due to over 1 million insects(invertebrates) are found there. Taxonomy is the classification of new and old species. Scientists determine this classification by studying the species deeply and intensely then comparing the species to other for which they are most alike. And deciding whether or not it was a species of their own or can go under a category.
ReplyDeleteScientists are not certain but there is 1.6 million specified but they predict around 7 million in all. Scientists determine where the species go in taxonomy by their genetic type or their physical appearance. Rain forests are considered to have the greatest mass of discovered species. But I believe the ocean contains the most biodiversity but we cannot prove this without being crushed. Areas around the equator are hot spots as well because they have a consistent temperature.
ReplyDeleteNo one knows for sure how many species there are on the Earth. One estimate is that there are anywhere between 5-50 million. The latest number for desribed species are 1.4 million. Another study shows that there are 270,000 plants and 1,324,000 animals. The majority are found in rainforests.
ReplyDeleteThey place animals in taxonomy based on there physical or cellular characteristics, genetic types, class, order, family, genus and species.
Rainforests have the most types of plants and animals. IT is said that about 50% of all species are found there and 25% of medicine comes from rainforests.
1.No one knows, but we've discovered about 1.5 million. There are probably a lot more. For example, we don't even know 1% of deep sea species.
ReplyDelete2.They used to determine them based on characteristics, but now its more DNA.
3.The rainforest has the most discovered species, but the deep ocean may have more. Coral reefs come in second. The rainforest also has a high rate of extinction because of deforestation.
no one knows exactly how many species of animals there is. Scientists predict that there is from 5 million to 30 million species. They place the animals in taxonomy by seeing what they have in common with other animals or what their similarities are. The majority of animals are found in rain forests like the Amazon Rainforest. The greatest ecosystem in the world is rain forests.
ReplyDeleteThere are around 375,000 plant species and 1.2 million animal species. The majority of the species are found in rain forests.
ReplyDeleteThe animals are placed in taxonomy based on similarities and differences in their DNA to the species already placed in taxonomy.
Rainforests have the most types of plants animals. Many newly discovered species are from rain forests and medicine also comes from the rain forests.
1. Scientists have only identified 2 million species on Earth, but the could be up to 100 million species present. Rainforests are the most diverse ecosystem on the Earth.
ReplyDelete2. Researchers take the organism and then try. To classify it. If the animal isn't classified similarly to. Any other species then a new species is created.
3. Rainforests are the most diverse in life on earth because of the climate.
As of right now, there are approximately two million species of organisms that have been discovered by humans. Despite this, scientists estimate that there are anywhere from five million to one hundred million species in existence.
ReplyDeleteNew organisms are placed in terms of their traits (both physical and behavioral), species (if it's similar to another species, they will place it where the similar species thrives) and, obviously, what kind of organism they are.
Rainforests are the most biodiverse places on Earth, containing about 50% of the world's known species. Unfortunately, the rainforests are being destroyed, which means biodiversity as we know it is also being destroyed!
Estimations range from 6 to 30 million, but only 1.6 million have been scientifically characterized, and the ocean.
ReplyDeleteBy concrete evidence like DNA, and the comparison and contrasting of the six or five kingdoms. They are then classified below the kingdom and domain with phylum, class, order, family, genus, and species.
On consensus, the tropical rainforest, especially the amazon, is considered to be the most biodiverse because of its extreme dependence on others, although still having thousands of species.
Since there are still both animal and plant species being found today, there is no exact number, so as far as actual animal and plant discovered there is about 1.5 million, but the esimate for how many species there are in the world counting the ones not discovered yet range from 2 million to 10 million. Most of these species our found in the rain forests of the world (majority through come from the amazon) and there are many new species being discovered everyday in that area. The rain forest also happens to contain biodiversity at the highest level, especially since so many animals live there. But coral reefs are also very diverse, and not much is known about deep ocean, not to mention that the rain forests are rapidly being depleted by deforestation, so this is always subject to change.
ReplyDeleteClassifying animals into different taxonomies is mostly based on there DNA and how it may be similar to different animals, and a bit on appearance and behavior, although this is not the most reliable method.
1) I discovered that there are about 1,740,330 discovered species of plants and animals on Earth. This, however, does not include single-celled organisms or domestic animals such as sheep and camels. Also, scientists feel there are far more to be discovered than we already have.
ReplyDelete2) Taxonomists place newly discovered organisms according to their natural properties and relationships.
3) The ecosystem with the greatest diversity is the tropical rainforest, with estimated 5-50 million species.
There is an estimated 2 million different species on Earth. This includes domesticated animals, wild animals, and bacteria. We only explore the surface of Earth though, so there could be millions more still undiscovered. We find most of these species in places where critical resources are.
ReplyDeleteScientists usually take a look at dna when placing a newly discovered animal in taxonomy. However, exterior features of an animal may also be important.
Yasuni National Park, a part of the Amazon Rainforest in Ecuador is the most biologically diverse location on Earth. You can see why, with it's thick forest of trees and rainy canopy. Birds, amphibians, reptiles, mammals, and insects are all found in the Amazon.
Note: insert "or more" after the 10 million.
ReplyDeleteThere is no exact number known for the amount of species found on earth. One estimate i said found that there are around 1.4 million species of animals and 321,212 species of plants. Estimates range all the way to 50 million. The majority of these are found in rainforests.
ReplyDeleteTaxonomists place animals based on their characteristics. They group them into class, order, family, genus, and species. Each group gets more and more specific.
The rainforest is considered to have the greatest biodiversity. It is so biodiverse that less than 1 percent of the rainforest's specie have been studied
From what I have found on the internet, there are about 1,250,000 identified species of animals in the world, and there about 375,000 species of plants in the world. So that comes out to a grand total of approximately 1,625,000 species of plants and animals in the world, but that probably not completely accurate, assuming we have discovered every species yet.
ReplyDeleteWell, considering taxonomy is the scientific classification of things, new plants and animals are placed accordingly based on there DNA, characteristics, class, family, species, physical appearance, etc.
The ecosystem with the most biodiversity on earth is considered to be the rain forest. With about half of the species on earth to be found there, it is very diverse. This is the way it is because the rain forest is a warm and moist place, so it can support many different types of life.
1. Scientists had discovered around 2 million species as of 2007. However, estimate place the actual total anywhere between 5 million and 100 million species alive today. Most of the oceans are still unexplored, so there are definitely many undiscovered animals residing underwater.
ReplyDelete2. The taxonomy system, invented in 1757, places animals in groups, from kingdom as the most broad to species as the smallest. The animals are categorized by characteristics they have in common.
3. The Amazon rainforest has the greatest biodiversity has the greets biodiversity of any other land area on Earth. Generally, the most biodiverse section of the Earth is near the equator, because of the mix of heat and humidity.
There are about 1.4-1.5 million species, give or take about .01 million. There is an estimated 45 million beings with life. Animals are placed in taxonomy based on their DNA from mitochondria and chloroplasts. The Amazon Rainforest is supposed to have the greatest alpha biodiversity in the world. There are an estimated 175,527 species in the Amazon Rainforest, including invertebrates. Many important medicines, like a possible cure for cancer, and endangered species, like the Golden Poison Dart Frog, come from this region. But sadly, deforestation is threatening the undiscovered wonders of this amazing micro-world.
ReplyDeleteI found that there are about 375,000 plant species and 1,250,000 animal species.
ReplyDeleteThe taxonomy of a plant is determined by how they look, their kingdom, phylum, class, order, family, genus, species.
The place with greatest biodiversity is the tropical forests.
1. As of right now scientists have discovered around 1.4 million species, though this number only scratches the surface of all of earth's species. Most are found in the tropical rainforest, seeing as it is the most biodiverse ecosystem on the planet.
ReplyDelete2. Scientists classify species based on their natural relationship to each other.
3. As mentioned previously, tropical rain forests are the most biodiverse ecosystems.
It's estimated that there are 2 million to 100 million but the best estimate is around 10 million species of organisms out there, but only 1.4 million have been named. The majority are found in the rainforest for the fact that it hasn't been explored as much as other habitats and for the fact that it's such a diverse community (Alpha, I think is what it would be called).
ReplyDeleteTaxonomy is the classification of organisms based on characteristics, similarities, origins, etc.
It's said that the rainforest has the most biodiversity. With deforestation, we are loosing 187 species a day with a total of 50,000 species a year. This goes to show how much biodiversity there is to loose 137 a day. Half of the world's estimated 10 million species live in the rainforest. A single pond in Brazil can contain a more fish diversity than all the rivers in Europe. 2.47 acres in the rainforest contain over 900 tons of living plants, 750 types of trees and 1500 other plant species. 1 in 5 birds in the world live in the rainforest.
The amount of plants and animals found in the world right now is about. 1.7 million. That's a lot of different species. Rain forests hold the highest diversity level for plants, animals, and others currently.
ReplyDeleteResearchers decide what a species is by using a taxonomic map, or a map of similarities that works by discovering the various likeness's of the different animals or plants.
The ecosystem that has the greatest biodiversity that I have found in the research done was a rainforest. It has the greatest biodiversity in the world currently.( according to various sites)
I think there are about 1.4 million species of plant and animals known, however not all species are known, and scientists discover new species all the time. By far the most species are found in the rain forests, thats because the rain forest is perfect for so many species.
ReplyDeleteBasically the scientists have to look at the habits, the diet, the appearance, and a lot of other stuff to try and classify the new species based on know species.
Rain forest (as I said before in paragraph numero uno) have by far the most plant, animal, and insect species. Rain forests are home to about 50% of all of all species in the world however we only know about half of the species in the world any way so that might not be accurate.
How many different species of plants and animals are there in the world and where are the majority of them found?
ReplyDeleteEstimates range from anywhere between 5 to 100 million, yet science has only discovered about 2 million species so far. Some believe that the most amount of different species are found in Costa Rica. About 500,000 species, almost 4% of the total estimated species worldwide, are in Costa Rica. About 300,000 of these are insects.
How do researches determine where new organisms are placed in taxonomy?
Taxonomy is the classification of new specimens into groups such as species through their heredity. Researchers and scientists look at their similarities to species already in existence in compare to if they are the same or if they belong to another group. They also look into their heredity and reproductive systems. Many animals can only breed with members of their own species, so that could easily classify them.
Which ecosystem is considered to have the greatest biodiversity?
The most differing animal species are said to be found in the Amazon Rainforest. This could possibly be due to the two very differing habitats in this rainforest; the canopy and the floor. These can support two groups with different needs.
1) 1.7 million species have been discovered on Earth as of 2010, but it has been described as only 80-90% of the true amount.
ReplyDelete2) Species are placed in taxonomy based on physical appearance and DNA.
3) Rainforests and oceans have the greatest amount of species and oceans probably have the most undiscovered.
How many different species of plants and animals are there in the
ReplyDeleteworld and where are the majority of them found?
It is estimated that there is about 1.5-2 million species on the Earth and this is including plants animals and bacteria. The majority of them are found in the rainforest, Such as the Amazon Rainforest.
How do researches determine where new organisms are placed in taxonomy?
Researches and scientists take the similarites that a species has and compares it to other species already discovered. The one it is most like in every aspect would typically be the species taxonomy.
Which ecosystem is considered to have the greatest biodiversity?
The ecosystem said to have the greatest biodiversity is the rainforest. The Amazon Rainforest is the major on that has the most biodiversity out of all of the different rainforests.
