The guts of cow and buffalo possess

Options

A. Cyanobacteria
B. Fucus spp
C. Chlorella spp
D. Methanogens

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the type of organisms present in the guts of cows and buffaloes.

2. **Identifying the Options**: The options provided are:
- Cyanobacteria
- Fucus species
- Chlorella species
- Methanogens

3. **Analyzing Each Option**:
- **Cyanobacteria**: These are photosynthetic bacteria that contain chlorophyll and can perform photosynthesis. They are not typically found in the guts of cows and buffaloes.
- **Fucus species**: This is a type of brown algae, which is a primitive organism found in marine environments. It is not related to the gut flora of cows and buffaloes.
- **Chlorella species**: These are green algae and are also not found in the guts of cows and buffaloes.
- **Methanogens**: These are anaerobic bacteria that thrive in environments without oxygen. They are known for producing methane by utilizing carbon dioxide and hydrogen gas.

4. **Conclusion**: The correct answer is **Methanogens**. These bacteria are essential for the anaerobic digestion of complex materials in the digestive systems of cows and buffaloes, allowing them to break down food efficiently.

### Final Answer: Methanogens
