2. Paper is a good example of a biodegradable pollutant as it acts as a pollutant when present in large quantities and not degraded at the right time.

Option B:

1. Pollutants that can be broken down by the activity of decomposers, and microorganisms and enter the biogeochemical cycles are called biodegradable pollutants.
2. Wood is an example of biodegradable pollutants as these pollutants are easily managed by natural processes or can be treated in treatment plants.

Option D:

1. Pollutants that can be broken down by the activity of decomposers, and microorganisms and enter the biogeochemical cycles are called biodegradable pollutants.
