Find out incorrect statement of DFC

Options

A. Starts with solar energy
B. Terminates in GFC
C. Requires specific detritivores
D. Plays major role in terrestrial systems

Answer

### Step-by-Step Solution:

1. **Understanding the Detritus Food Chain (DFC)**:
- The DFC is a type of food chain that begins with the decomposition of dead organic matter, which can be plant or animal remains.

2. **Identifying the Energy Source**:
- Unlike other food chains that start with solar energy, the DFC starts with the chemical energy stored in dead bodies. This energy is released during the decomposition process.

3. **Role of Decomposers**:
- Decomposers, such as bacteria and fungi, break down the complex organic matter into simpler forms, releasing energy and nutrients back into the ecosystem.

4. **Energy Flow Rule**:
- The DFC does not follow the 10% energy flow rule, which is typically applicable to grazing food chains. This makes it an exceptional food chain.

5. **Connection to Grazing Food Chain (GFC)**:
- The DFC can connect to the GFC, as some decomposers may be consumed by organisms in the grazing food chain, such as humans eating mushrooms.

6. **Evaluating Statements**:
- The question asks to find the incorrect statement regarding the DFC.
- The first statement, "starts with solar energy," is incorrect because the DFC starts with the decomposition of dead matter, not solar energy.

7. **Conclusion**:
- The correct answer to the question is that the first statement is incorrect.
