Marsh gas is produced by

Options

A. Mycoplasma
B. Myxobacteria
C. Methanogens
D. Halophiles.

Answer

**Step-by-Step Solution:**

1. **Understanding Marsh Gas**: Marsh gas is commonly referred to as biogas and is primarily composed of methane. It is also known as methane gas due to its significant methane content.

2. **Composition of Marsh Gas**: In addition to methane, marsh gas contains small amounts of other gases such as hydrogen sulfide and carbon dioxide.

3. **Formation Process**: Marsh gas is produced through the decomposition of organic matter, specifically vegetable matter, in an anaerobic environment (absence of oxygen).

4. **Role of Microorganisms**: The decomposition process is facilitated by certain types of bacteria, particularly anaerobic bacteria.

5. **Identifying the Correct Organism**: Among the given options (mycoplasma, myxobacteria, methanogens, and halophiles), the organisms responsible for the production of marsh gas are methanogens. These are a specific group of archaea that produce methane as a metabolic byproduct.

6. **Conclusion**: Therefore, the correct answer to the question "Marsh gas is produced by" is **methanogens**.
