Question

the nutrient levels in rainforest soils are concentrated at the surface of the soil. because of this, what happens once rainforests are cleared? the soils are nutrient rich for many generations the soils deteriorate quickly

Explanation:

In rainforests, nutrients are at the soil surface. When cleared, there's no canopy to protect the soil. Rain washes away nutrients (leaching), and without plants to recycle nutrients (like in the rainforest nutrient - cycling process), the soil quality drops fast. So, the soil deteriorates quickly.

Answer:

The soils deteriorate quickly
