Answer 1

The correct option is A Biodegradable substances can be broken down into simpler substances by biological processes.

Non-biodegradable substances cannot be broken down into simpler ones by biological processes.

Substances that can be broken down into simpler substances by biological processes (for example, decomposition by decomposers like bacteria, fungi, etc.) are said to be biodegradable. For example, wood, paper, etc.

Substances that cannot be broken down into simpler ones by biological processes are said to be non-biodegradable. For example, plastic, DDT, etc.
