Define biodegradation

Biodegradation is the process by which organic substances are broken down by living organisms, such as bacteria, fungi, and other simple decomposers, into simpler compounds.

Analyze environmental factors

Decomposition by living organisms generally requires moisture and warmth. Therefore, biodegradable substances decompose slower, not faster, in dry places or at low temperatures. This rules out the first two options.

Evaluate decomposer types

The biological breakdown is carried out by living organisms (biotic factors) rather than purely abiotic chemical reactions with inorganic compounds. This makes the third option correct and the fourth option incorrect.
