Which of the following show anaerobic respiration ?

Options

A. Earthworms
B. Rabbit
C. Echinderms
D. Tapeworms

Answer

### Step-by-Step Solution:

1. **Understanding Anaerobic Respiration**:
- Anaerobic respiration occurs in the absence of oxygen. It is a type of respiration that some organisms use to generate energy when oxygen is not available.

2. **Types of Respiration**:
- There are two main types of respiration:
- **Aerobic Respiration**: Requires oxygen and produces more energy.
- **Anaerobic Respiration**: Does not require oxygen and generally produces less energy.

3. **Identifying Organisms**:
- The question provides four options: Earthworm, Rabbit, Echidna, and Tapeworm. We need to determine which of these organisms can perform anaerobic respiration.

4. **Analyzing Each Option**:
- **Earthworm**: This organism lives in soil and requires oxygen for respiration. It performs aerobic respiration.
- **Rabbit**: A mammal that also requires oxygen for its metabolic processes and performs aerobic respiration.
- **Echidna**: Another mammal that breathes oxygen and relies on aerobic respiration.
- **Tapeworm**: A parasitic organism that lives inside a host and does not have direct access to oxygen. It relies on anaerobic respiration (fermentation) to generate energy.

5. **Conclusion**:
- Among the options provided, the only organism that shows anaerobic respiration is the **Tapeworm**.

### Final Answer:
The organism that shows anaerobic respiration is **Tapeworm**.
