Which one of the following options is correct in respect …

Correct Answer: Statement-I is incorrect but Statement-II is correct

Explanation:

1. Statement-I: “The soil in tropical rain forests is rich in nutrients.”
   Incorrect.
   The soil in tropical rainforests is typically poor in nutrients. This is because heavy rainfall causes leaching, washing away nutrients from the topsoil. Most of the nutrients in tropical rainforests are found in the biomass (plants and trees) rather than in the soil.
2. Statement-II: “The high temperature and moisture of tropical rain forests cause dead organic matter in the soil to decompose quickly.”
   Correct.
   Tropical rainforests experience warm and humid conditions, which accelerate the decomposition of organic matter. This rapid decomposition ensures that nutrients are quickly absorbed by plants, leaving little in the soil.

Conclusion:

The soil in tropical rainforests is nutrient-poor, despite the rapid decomposition of organic matter due to the high temperature and moisture.
Thus, Statement-I is incorrect, but Statement-II is correct.
