Question

Which of the following waste cannot be considered as a soil pollutant?

• A. Biodegradable
• B. Non-biodegradable
• C. Industrial
• D. All of the above

Answer 1

The correct option is A Biodegradable

Substances that are not broken down by microorganisms are non-biodegradable. Non-biodegradable substances affect the soil. Biodegradable substances are broken down by organisms and are not harmful to environment. Hence, non-biodegradable and industrial wastes are considered as soil pollutants. They may enter the food chain and harm the organisms in the higher trophic levels.

Thus, the correct answer is option A.
