What could be the reason for the faster rate of decomposition in the tropics? 

Explanation

**Step-by-Step Solution:**

1. **Understanding Decomposition**: Decomposition is the process through which dead organic matter is broken down by microorganisms, fungi, and other decomposers. This process is crucial for nutrient cycling in ecosystems.

2. **Identifying the Environment of the Tropics**: The tropics are characterized by a hot and humid climate. This means that temperatures are generally high, and there is a significant amount of moisture in the air.

3. **Role of Temperature**: High temperatures in the tropics create an optimal environment for the activity of decomposers. Microorganisms, such as bacteria and fungi, thrive in warm conditions, which accelerates their metabolic processes.
