Koeppens Classification

The tropical rainforest is a complex ecosystem with a high level of biodiversity. When a tropical rainforest is removed, it does not regenerate quickly as compared to a tropical deciduous forest. This is primarily due to the fact that the soil of the rainforest is deficient in nutrients. The high rainfall in these areas washes away the nutrients from the soil, making it less fertile. The other options, such as poor viability of propagules, slow-growing species, and invasion by exotic species, may also contribute to the slow regeneration, but the primary reason is the nutrient-deficient soil.

* **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.
