Why do most soils in tropical rain forests hold few plant nutrients? why do temperate deciduous forests typically have a thick layer of decaying litter?

Answered

Explanation:

Tropical rain forests are found near the equator, where hot, moisture-laden air rises and dumps its moisture. The lush forests have year-round, uniformly warm temperatures, high humidity, and almost daily heavy rainfall. Tropical rain forests are dominated by broad leaf evergreen plants. Since, there is adequate temperature and sufficient rainfall, favorable conditions for the decomposers  to prevail hence, soils in tropical rain forests hold few plant nutrients.

Forest is the temperate deciduous forest. Because they have cooler temperatures and fewer decomposers than tropical forests have, these forests also have a slower rate of decomposition.
