Which one produce gas by decomposing the gobar (Dung) in gobar gas

Options

A. Fungus
B. Virus
C. Methanogenic bacteria
D. Algae

Answer

To answer the question, "Which one produces gas by decomposing the gobar (dung) in gobar gas?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Components**:
- Gobar gas is produced from the decomposition of organic matter, specifically dung (gobar).
- The question asks which organism is responsible for this decomposition process.

2. **Identifying the Organisms**:
- The options provided are fungus, virus, methanogenic bacteria, and algae.
- Each of these organisms has different roles in the ecosystem.

3. **Analyzing Each Option**:
- **Fungus**: While fungi decompose organic matter, they primarily break down complex organic materials and do not produce biogas.
- **Virus**: Viruses do not decompose organic matter; they infect living cells and are not involved in the decomposition process.
- **Methanogenic Bacteria**: These are a specific group of bacteria that thrive in anaerobic (oxygen-free) environments and are known for breaking down organic matter, producing methane and carbon dioxide as byproducts.
- **Algae**: Algae are photosynthetic organisms and do not play a role in the anaerobic decomposition of dung.

4. **Conclusion**:
- The correct answer is **methanogenic bacteria**. They are responsible for the anaerobic digestion of organic materials, including dung, leading to the production of biogas (gobar gas).

### Final Answer:
The organism that produces gas by decomposing the gobar (dung) in gobar gas is **methanogenic bacteria**.
