Methane is produced as which type of decomposition product?

Methane is produced as which type of decomposition product?

• A. Gas end product
• B. Liquid end product
• C. Solid end product
• D. Enzyme

Answer: (A)

End products of decomposition are categorized by their physical state, and methane is produced as a gaseous end product in anaerobic digestion. In environments without oxygen, certain microorganisms (methanogens) break down organic matter and release methane along with carbon dioxide as the main gases. Since methane exists as a gas at typical conditions, it’s classified as a gas end product. It’s not a liquid or solid, and it’s not an enzyme. This gaseous form is what lets methane be collected as biogas for energy use.
