fermentation
oxidation
aerobic respiration
reduction
Answer is Wrong!
Answer is Right!
The correct answer is: A. fermentation
Fermentation is a metabolic process that produces chemical changes in organic molecules without the use of oxygen. This type of anaerobic respiration occurs in many different types of organisms, including bacteria, yeast, and some plants.
Biogas is a gas produced by the breakdown of organic matter in the absence of oxygen. It is a mixture of methane, carbon dioxide, and other gases. Biogas can be used as a fuel for heating, cooking, and electricity generation.
The other options are incorrect because they do not describe the process of biogas production.
- Oxidation is a chemical reaction that involves the loss of electrons. It is the opposite of reduction.
- Aerobic respiration is a metabolic process that uses oxygen to produce energy. It is the most efficient way for organisms to produce energy.
- Reduction is a chemical reaction that involves the gain of electrons. It is the opposite of oxidation.
