Question

What are methanogens? How do they help to generate biogas?

Answer 1

Hint: Bacteria are organisms that help to break down many substances in our environment which is extremely useful for the biological process that go on in our ecosystem. Methanogens are bacteria that produce methane by breaking down plant material.

Complete answer:
These methanogens are microorganisms that are able to break down material that contains cellulose. The primary component of the plant cell wall is cellulose. Therefore when plant material is decomposing these bacteria can help to break it down and this entire process generates methane.
Biogas mainly consists of carbon dioxide and methane. This biogas can be used as a source of gas to run vehicles and so on. In order to produce this gas, manufacturers break down organic material with bacteria. The methanogens are used here to break down this cellulose. This cellulose is usually found in waste like cow dung, food waste or other factory waste. These bacteria are also used to break down sewage waste.
Once the organic matter is broken down the biogas that is produced can then be used as an energy source. Biogas is able to be used in many industries to cook, produce electricity, etc. It is a green source of energy that is renewable.

Note:
Methanogens are bacteria that produce methane. These bacteria can break down cellulose and other organic matter that is found in plant waste. The bacteria is used to produce biogas that is produced can then be used as a renewable energy source.
