Question

Substances which cannot be decomposed by micro-organisms are called non-biodegradable substances.

• A. True
• B. False

Answer 1

The correct option is A True

Biodegradable substances can be degraded by natural factors like microbes (e.g. bacteria, fungi, etc.), abiotic elements like temperature, UV, and oxygen.

On the other hand, non-biodegradable substances like plastics cannot be decomposed or dissolved by natural agents like micro-organisms.
