Question

The main end products of anaerobic digestion of organic waste are:

• A. COsubscript{2} and Hsubscript{2}O
• B. Methane (CHsubscript{4}) and COsubscript{2}
• C. Nitrates and sulfates
• D. Oxygen and biomass

Hint:

In anaerobic digestion, remember that methane and carbon dioxide are the key products, whereas oxygen and biomass are consumed during the process.

Answer 1

The Correct Option is B

In anaerobic digestion, microorganisms break down organic waste in the absence of oxygen, producing biogas. The main components of this biogas are methane (CH₄) and carbon dioxide (CO₂). This process is commonly used in waste treatment and biogas production. The other options, such as nitrates and sulfates, are not typical end products in anaerobic conditions.
