Question

‘‘Excessive use of chemicals and pesticides in agriculture adversely effect the environment.’’ Justify this statement.

Accepted Answer

Chemicals/pesticides used by farmers get washed down into the soil or water bodies and affect biotic and abiotic components of the ecosystem. These chemicals are mostly non-biodegradable and get accumulated progressively at each trophic level (Biological magnification). Thus, the health of the organisms of all trophic levels is affected.
