Statement-Il: The high temperature and moisture of tropical rainforests cause dead organic matter in the soil to decompose quickly.

Which one of the following is correct in respect of the above statements?

2. Both Statement-I and Statement-Il are correct and Statement-Il is not the correct explanation for Statement-I
3. Statement-I is correct but Statement-II is incorrect
4. Statement-I is incorrect, Statement-II is correct

Answer (Detailed Solution Below)

Option 4: Statement-I is incorrect, Statement-II is correct

Detailed Solution

Explanation:

The soils of the tropical rainforest are typically nutrient-poor. The high temperature and moisture of tropical rainforests cause dead organic matter in the soil to decompose quickly. In tropical rainforests, the plants grow so fast that they quickly consume the nutrients from the soil, and the leftover nutrients are then leached away by abundant rainfall, which leaves the soil infertile. So, statement 1 is not correct and statement 2 is correct.

Therefore, option (4) is the correct answer.
