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
(d) Statement-I is incorrect but StatementII is correct
Answer: (d)
Statement 1 is incorrect: Tropical rainforest soils may not be considered rich in all nutrients, they are highly productive and support diverse and abundant plant life. The complex interactions between plants, microorganisms, and nutrient cycling processes contribute to the overall fertility and resilience of rainforest ecosystems.
Statement 2 is correct: The combination of high temperature and moisture in tropical rainforests creates favourable conditions for the rapid decomposition of dead organic matter in the soil. This process is known as decomposition or decay.The warm and humid climate in tropical rainforests accelerates the activities of decomposer organisms such as bacteria, fungi, and other microorganisms. These decomposers break down organic matter, including fallen leaves, twigs, dead plants, and animal remains, into simpler compounds and nutrients.
