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

Answer

To answer the question about what organism A could be, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Role of Organisms A and B**:
- Organisms A and B are found on the forest floor and are responsible for converting dead plant parts and dead bodies of animals into simpler substances.

2. **Identifying the Process**:
- The process described involves breaking down complex organic matter (like dead plants and animals) into simpler substances. This process is known as decomposition.

3. **Recognizing the Type of Organisms Involved**:
- The organisms that perform decomposition are typically known as decomposers. Decomposers include bacteria, fungi, and some insects.

4. **Focusing on Organism A**:
- Since we need to identify specifically organism A, we can consider the most common and significant decomposers in forest ecosystems.

5. **Choosing a Specific Example**:
- Among decomposers, bacteria are one of the most abundant and essential organisms that break down dead organic matter. Therefore, organism A could be bacteria.

6. **Conclusion**:
- Based on the information provided and the role of decomposers, organism A is likely to be bacteria.

### Final Answer:
**Organism A could be bacteria.**
