Reason (R): Heavy continuous rainfall leaches soluble nutrients deep into the soil, while the rapid bacterial action quickly decomposes any organic matter on the surface.
Explanation
Heavy precipitation in tropical regions causes severe leaching, which removes essential minerals and nutrients from the soil, leaving it acidic and nutrient-poor. Simultaneously, high temperatures and humidity promote extremely rapid bacterial decomposition. This ensures that any organic matter falling to the forest floor is quickly broken down and immediately reabsorbed by the dense vegetation biomass, rather than accumulating.Explanation
