The organisms A and B occur on the forest floor. They convert the dead parts of forest plants and dead bodies of forest animal into simple substances such as C,D and E which can be re-used by organisms F for their growth and development.
What is the general name of organisms like A and B?

Answer

To answer the question, we need to identify the general name of organisms A and B, which are found on the forest floor and are responsible for converting dead plant and animal matter into simpler substances.

### Step-by-Step Solution:

1. **Identify the Role of Organisms A and B**:
- Organisms A and B are described as converting dead parts of forest plants and dead bodies of forest animals into simpler substances.

2. **Understand the Process**:
- The process of breaking down dead organic matter involves decomposition, where complex organic materials are broken down into simpler substances.

3. **Recognize the Importance of This Process**:
- The simpler substances produced (C, D, and E) are essential for the growth and development of other organisms, specifically organism F, which likely refers to plants.

4. **Define the General Name for A and B**:
- Organisms that perform the function of breaking down dead organic matter are known as decomposers. They play a crucial role in nutrient cycling within ecosystems.

5. **Conclusion**:
- Therefore, the general name for organisms A and B is **decomposers**.
