Aquatic plant used in bioigas generation is

Options

A. Eichhorina
B. Typha
C. Potamogeton
D. Vallisneria

Answer

**Step-by-Step Solution:**

1. **Understanding Biogas Production**: Biogas is a renewable energy source produced through the anaerobic digestion of organic matter. It primarily consists of methane (CH4), carbon dioxide (CO2), hydrogen, and hydrogen sulfide.

2. **Role of Methanogens**: The production of biogas is facilitated by a group of bacteria known as methanogens. These bacteria decompose organic matter, converting it into biogas.

3. **Identifying Aquatic Plants**: The question specifically asks for an aquatic plant that can be used in biogas production. Various aquatic plants can be considered, but not all are suitable for this purpose.

4. **Evaluating Options**: The provided options include:
- A) Ichnoria
- B) Typha
- C) Potamogeton
- D) Valisneria

5. **Selecting the Correct Plant**: Among the options, Ichnoria (often referred to as Eichhornia or water hyacinth) is known for its high biomass production and is commonly used in biogas generation due to its ability to decompose effectively.

6. **Conclusion**: Therefore, the aquatic plant used in biogas generation is **Ichnoria**.

**Final Answer**: Ichnoria
