Different between biodegradable and non biodegradable pollutants?                                                           class 12th CBSE biology sampme paper

Answer 1

Biodegradable Pollutants:

i. They are decomposed and degraded by microbes

ii. Degradation process is rapid.

iii. They are not accumulated but are used up in short time.

iv. They are used to produce energy manure, compost and biogas.

v. They become part of biogeochemical cycles and give back rapid turn over

Non-Biodegradable Pollutants:

i. Cannot be decomposed by microbes.

ADVERTISEMENTS:

ii. Degradation process is slow.

iii. They often accumulate.

iv. They can be separated and recycled but the process is very expensive.

v. Most of them never enter into Biogeochemical cycles, very slow and toxic.

Answer 2

Biodegradable pollutants:

1)These are decomposed and degraded by microbal action'

2)They are degraded quick rapidely.

3)They do not pile up.

Examples : garbage, sewage, livestock, wastes.

Non-Biodegradable pollutants:

1)They are not decomposed by microbes.

2)These are degraded very slowly.

3)They often accumulate.

Examples : Plastics, Polyethylene, broken glass, cans, etc.
