Decomposition is

Options

A. The process of recycling of nutrient in the ecosystem
B. Anaerobic process
C. Faster if detritus is rich in lignin and chitin
D. Slower in warm and moist enviroment

Answer

To solve the question "Decomposition is," we need to analyze the given options and determine which one correctly describes the process of decomposition.

### Step-by-Step Solution:

1. **Understanding Decomposition**:
- Decomposition is the process where complex organic compounds are broken down into simpler inorganic substances, such as carbon dioxide (CO2), water, and nutrients. This process is essential for recycling nutrients in the ecosystem.

2. **Evaluating the Options**:
- **Option A**: "The process of recycling of nutrients in the ecosystem."
- This statement is correct. Decomposition indeed recycles nutrients, allowing for the continuation of life processes in the ecosystem.

- **Option B**: "Anaerobic process."
- This statement is incorrect. Decomposition is primarily an aerobic process, which means it requires oxygen. While some decomposition can occur anaerobically, the general process is aerobic.

- **Option C**: "Faster if detritus is rich in lignin and chitin."
- This statement is also incorrect. Decomposition is slower if detritus is rich in lignin and chitin, as these compounds are more resistant to breakdown. In contrast, materials rich in nitrogen and water-soluble sugars decompose faster.

- **Option D**: "Slower in warm and moist environment."
- This statement is incorrect. Warm and moist environments actually promote faster decomposition. Cooler temperatures can slow down the decomposition process.

3. **Conclusion**:
- After evaluating all the options, the correct answer is **Option A**: "The process of recycling of nutrients in the ecosystem."

### Final Answer:
Decomposition is the process of recycling of nutrients in the ecosystem.
