What is the difference of fermentation and decomposition?

Answer 1

Decomposition uses cellular respiration to break down dead plant matter--this means that oxygen is involved in the process. Fermentation is another word for anaerobic decomposition, which occurs without oxygen.

Answer 2

Fermentation is the process by which microorganisms break down organic compounds in the absence of oxygen to produce energy, such as in the production of alcohol or yogurt. Decomposition is the process by which organic matter is broken down into simpler substances by bacteria and fungi in the environment, releasing nutrients back into the ecosystem. Both processes involve the breakdown of organic matter, but fermentation typically involves specific microorganisms producing a specific end product, while decomposition is a more general process in nature.
