Answer:

The natural vegetation depend upon the climate conditions of a place. The Amazon River basin, being a large supporter of species, also experiences climatic variations. For example evergreen forests grow in the region which experience heavy rainfall. Plant growth is dense.

Only little sunlight reaches the ground due to the dense roof canopy by the creepers and plants. The ground remains dark and damp and only shade-tolerant vegetation will grow here.

Even the global climate may have varied if the Amazon Basin wasn't there. The plants grow hanging onto the branches or tree trunks with aerial roots, not as parasites but as epiphytes. Species of tropical trees native to the Amazon include Brazil nut, rubber tree and Assai palm.

Hence, if there was no rain or cool temperature in the Amazon Basin, then there would not have been such varieties of species.
