Question

6) What are the characteristics of biogas?
7) Why should we conserve forests and wildlife?
8) What is positive geotropic movement and negative geotropic movement?​

Answer 1

Answer:

6) The gases methane, hydrogen, and carbon monoxide (CO) can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel; it can be used for any heating purpose, such as cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat.

Answer 2

Answer:

Biogas is comprised primarily of methane and carbon dioxide. It also contains smaller amounts of hydrogen sulphide, nitrogen, hydrogen, methylmercaptans and oxygen. Biogas originates from bacteria in the process of bio-degradation of organic material under anaerobic (without air) conditions.
