Raw material for decompostion represented by dead organic matter is

Options

A. Detritus
B. Only roots
C. Minerals
D. Humus

Answer

To solve the question regarding the raw material for decomposition represented by dead organic matter, we will follow these steps:

### Step-by-Step Solution:

1. **Understand Decomposition**:
- Decomposition is the process of breaking down organic matter into simpler organic or inorganic substances. This process is essential for recycling nutrients in ecosystems.

2. **Identify the Role of Decomposers**:
- Decomposition is carried out by various microbes and organisms known as decomposers. These organisms feed on dead organic matter.

3. **Define Raw Material for Decomposition**:
- The raw material for decomposition refers to the starting material that decomposers utilize to break down and recycle nutrients. This includes the remains of dead plants and animals.

4. **Terminology for Dead Organic Matter**:
- The specific term used for the dead organic remains (the raw material for decomposition) is "detritus." Detritus includes any organic particulate matter that is dead.

5. **Evaluate the Options**:
- The options given are:
- A) Detritus
- B) Only roots
- C) Minerals
- D) Humus
- Among these, "detritus" is the correct answer as it specifically refers to the dead organic matter that serves as the raw material for decomposition.

6. **Conclusion**:
- Therefore, the correct answer to the question is **detritus**.
