UPSC 2023: Consider the following statements: Statement-I: The soil in tropical rain forests is rich in nutrients. Statement-II: The high temperature and moisture of tropical rain forests cause dead organic matter in the soil to decompose quickly. Which one of the following is correct in respect of the above statements?
(a)Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
(b)Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
(c)Statement-I is correct but Statement-II is incorrect

Attempt This Question
Not attemptedCorrect Answer: (d) Statement-I is incorrect but Statement-II is correct
Tropical rain-forest soils are heavily leached oxisols/laterites that are poor in available nutrients; nutrients reside mainly in the living biomass, so Statement I is incorrect. High temperature and moisture accelerate microbial activity, causing rapid decomposition of litter; Statement II is correct and explains the swift nutrient cycling that prevents accumulation in the soil. Thus Statement I is wrong while Statement II is right.
