The rain forest has many plants and animals, more than half the entire world’s population. It contains more animals than you or I could ever count. It contains ferns, a whole bunch of different varieties of trees. It also has more than three quarters of the entire world’s population of insects. But many of these insects will only live in certain places inside or on the trees and plants. Some ants will be found in one kind of tree, and they eat the inside of it while living in it.
The rain forest is one of the many different kinds of biomes, but it contains more plants and animals than any other kind of biome alone.
