Answer:
Biodegradation is the naturally-occurring breakdown of materials by microorganisms such as bacteria and fungi or other biological activity. Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances.
Biotransformation is the process by which a substance changes from one chemical to another (transformed) by a chemical reaction within the body.Biotransformation is the process by which a substance changes from one chemical to another (transformed) by a chemical reaction within the body. Metabolism or metabolic transformations are terms frequently used for the biotransformation process.
Explanation:
Biotransformation plays a key role in modulating the toxicities of VOCs. Many VOCs are poorly soluble in water and the metabolism converts them to relatively water-soluble derivatives, which may be more readily eliminated in the largely aqueous urine and/or bile.
Biodegradation is nature's way of recycling wastes, or breaking down organic matter into nutrients that can be used by other organisms. In this case the purpose is to break down organic matter so that it will not cause pollution problems when the water is released into the environment.
