NEET BIOLOGY

Detailed explanation-1: -Biogas is generated during anaerobic digestion when microorganisms break down (eat) organic materials in the absence of air (or oxygen). Biogas is mostly methane (CH4) and carbon dioxide (CO2), with very small amounts of water vapor and other gases.

Detailed explanation-2: -Anaerobic digestion is a series of biological processes in which microorganisms break down biodegradable material in the absence of oxygen. One of the end products is biogas, which is combusted to generate electricity and heat, or can be processed into renewable natural gas and transportation fuels.

Detailed explanation-3: -The anaerobic digestion process produces gas composed of methane (CH4) and carbon dioxide (CO2), known as biogas. These gases are produced from organic wastes such as livestock manure, food processing waste, etc.

Detailed explanation-4: -During this digestion, bacteria produce a mixture of gases such as methane, hydrogen sulphide and carbon dioxide. These gases form biogas.

Detailed explanation-5: -Digested sludge contains an association of anaerobic fermentation and methanogenic bacteria producing carbon dioxide and methane.
