Combustible gas used as cooking gas in agricultural communities.

Answer 2

Answer:

Biogas is a fuel, which is obtained by the decomposition of the organic waste.

Explanation:

• To obtain the biogas, organic waste like animal waste, leftover food or rotten vegetables, leaves etc, are left to break down in the absence of oxygen.
• When the organic matter breaks down it produces a mixture of gases, mainly "methane and carbon dioxide".
• Biogas is an eco-friendly and renewable source of energy. It burns out with a "blue flame". By generating biogas we are reducing the soil as well as water pollution.
