Question

what happens to tropical rainforest soils when the rainforest is cleared? the soils are far more productive than other ecosystems. the soils deteriorate quickly and are progressively less productive. the soils increase in quality. crops can be grown for many, many years without nutrient supplements.

Explanation:

Tropical rainforest soils rely on the forest ecosystem for nutrient cycling. When cleared, without the forest's canopy and root systems, heavy rainfall leaches nutrients, and soil structure is damaged. This leads to rapid deterioration and reduced productivity.

Answer:

The soils deteriorate quickly and are progressively less productive.
