Question

Name the process by which biogas is produced from cattle dung.

Answer 1

The correct answer is:

1. The cattle dung is decomposed into biogas in the absence of oxygen (or without using oxygen) by anaerobic bacteria.
2. Any chemical reaction that occurs due to the absence of oxygen (or without using oxygen) is called an anaerobic reaction.

Hence, the process by which biogas is produced from cattle dung is called an Anaerobic reaction.
