• Statement I is incorrect: The soil in tropical rainforests is not rich in nutrients. The heavy rainfall in these regions washes away the nutrients from the soil, preventing them from accumulating.

• Statement II is correct: In tropical rainforests, high temperature and humidity help dead plants and animals decompose quickly. The warmth and moisture create the perfect conditions for bacteria and fungi, which are tiny organisms that break down dead material. These decomposers work faster in such an environment, turning dead matter into nutrients that go back into the soil to support new plant growth.

Therefore, Statement-I is incorrect but Statement-II is correct.
