What is the vegetation of Amazon basin?
The vegetation of the Amazon basin is mainly rainforest. This is a tall closed canopy forest with strong shading and little understory vegetation, except in areas where trees have fallen. In general the soil is poor and roots do not penetrate deeply, so larger trees do fall quite frequently.
What have farmers in the Amazon River Basin found to be the cause of reductions in the soil's fertility?
The word "basin" refers to the portion of a valley from which water drains into the river, and then to the sea. The Amazon Basin is another way to refer to the Amazon River Valley in northern and central South America. The basin is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela. It is not a closed basin, but flows into the Atlantic Ocean at the river's mouth.
