Question
How many different species of plants and animals are there in the Tropical Rain Forest biomes.

Answer
 If you mean every species of plant and animal this is a tough question to answer because the best guess would only be a rough estimate.    We could say a million or 10 million.  This is because there are so many different insects. One biologist sampled all the insects in a single tree and found 2000 new species.  When he checked another tree he found 2000 more new species. Every tree 2000 new species. And consider how many trees there are.
