In anaerobic sludge digesters during digestion, bacteria produce mixture of gases called biogas . Give the three example of components of biogas.

Answer

**Step-by-Step Solution:**

1. **Understanding Anaerobic Digestion:**
- Anaerobic digestion is a process that occurs in the absence of oxygen (O2). During this process, organic matter is broken down by microorganisms.

2. **Role of Microorganisms:**
- Specific types of bacteria, known as methanogens, play a crucial role in this digestion process. They help decompose organic matter and produce biogas as a byproduct.

3. **Components of Biogas:**
- Biogas is primarily composed of several gases. The three main components of biogas are:
- **Methane (CH4):** This is the primary component and is responsible for the energy content of biogas.
- **Carbon Dioxide (CO2):** This gas is produced alongside methane during the anaerobic digestion process.
- **Hydrogen Sulfide (H2S):** Although present in smaller quantities, hydrogen sulfide is another component of biogas.

4. **Conclusion:**
- Therefore, the three examples of components of biogas produced in anaerobic sludge digesters are:
- Methane (CH4)
- Carbon Dioxide (CO2)
- Hydrogen Sulfide (H2S)
