Decomposers are also called as

Options

A. transducers
B. reducers
C. micro-consumers
D. both b and c

Explanation

### Step-by-Step Solution:

1. **Understanding Decomposers**:
- Decomposers are organisms that break down dead organic matter, converting it into simpler inorganic substances. This process is essential for nutrient cycling in ecosystems.

2. **Analyzing the Options**:
- The question provides several options to identify what decomposers are also called.

3. **Option A - Transducer**:
- Transducers convert energy from one form to another. This definition does not align with the function of decomposers. Therefore, this option is incorrect.

4. **Option B - Reducer**:
- Reducers are organisms that degrade dead bodies of other organisms. This function is similar to that of decomposers, as both break down organic matter. Thus, this option is correct.

5. **Option C - Micro-consumers**:
- Decomposers are often smaller in size and are referred to as micro-consumers due to their role in consuming organic matter at a microscopic level. This option is also correct.

6. **Final Conclusion**:
- Since both options B (Reducer) and C (Micro-consumer) accurately describe decomposers, the correct answer is option D, which states that decomposers are also known as both B and C.
