Why Do Tropical Rainforests Exist in Soils That are Nutrient-Poor

Question

Why do tropical rainforests exist in soils that are nutrient-poor?
A) There is a low rate of decomposition, and plants cannot absorb the "undigested" nutrients.
B) There is a low rate of decomposition, and plants quickly absorb the nutrients as they are available.
C) There is a high rate of decomposition, and plants quickly absorb the nutrients as they are available.
D) The plants cannot use the types of nutrients produced by tropical decomposers.

Accepted Answer

Tropical rainforests have a high rate of decomposition due to the warm and moist conditions, which facilitate rapid breakdown of organic matter. The nutrients released from decomposition are quickly absorbed by the dense vegetation, leaving the soil itself relatively nutrient-poor.
