Question

The fuel gas which can be made by some bacteria that are some decomposers is:

1. oxygen
2. carbon monoxide
3.hydrogen
4. methane

Answer 1

Methane

Step-by-step explanation:

When the oxygen available below ground is used up by fungi and bacteria, their decomposing activity stops. Easily decomposed organic substances will continue to be broken down by anaerobic bacteria, which can live where no oxygen exists. Methane gas is one of the products of their decomposing activity.
