Answer 1

Answer:

organic materials

Explanation:

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.

Answer 2

Answer:

biogas is a mixture of methane and carbon dioxide.

Explanation:

Biogas is actually a mixture of components in which methane (45%–75%) and carbon dioxide (25%–50%) dominate, together with water vapor (1%–5%), nitrogen (0%–5%), and lower amounts of ammonia and hydrogen sulfide, as well as trace amounts of hydrogen and carbon monoxide.
