Rainforest soils are characterized by what true statement about nutrients?

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

In rainforest soils, the amount of nutrients actually available in the mineral soil is low, even though the ecosystem is very productive. This happens because heavy rainfall leaches soluble nutrients from the soil and most essential nutrients are stored in the living plants and in the litter layer, where they cycle rapidly back to vegetation. So, nutrient availability in the soil is limited, while the ecosystem relies on fast nutrient turnover and storage in biomass. That’s why the statement is true: rainforest soils are nutrient-poor in the soil despite high productivity. The other options imply uncertainty or variability that doesn’t reflect this general pattern.
