But each will also have a distinct group of animal species as well. For example, spadefoot toads exist only in the desert biome because they have developed special adaptations to exist in these dry conditions. Location in Amazon basin, central America, Congo Basin, Indonesia and southeast Asia. Found in equatorial and tropical latitude zones Consist of tall, closely set trees , sometimes over 40 meters, that form a continuous canopy, and dense shade underneath Trees are smooth-barked, very large in girth, and evergreen. Form three continuous layers, with the emergent layer being on top Epiphytes are common, also called air plants.
Lianas are very common and can be very thick.
Large number of different tree species , some that haven't been identified yet High temperatures, and plentiful moisture cause rapid decomposition of plant matter, such that the soils are not enriched inorganic matter. Rainforests are not composed of impenetrable jungle . Rather, the forest floor of rainforests is actually quite open because of the dense shade that occurs in rainforests. A major problem facing rainforests is continuous and heavy use by humans in need of agricultural land. Because the rainforest floor is not very rich in nutrients, most land is used only for a few seasons before the farmers move on.
