Answer

Answer:

A. Fertilizer used for agriculture can enter bodies of water, causing eventual oxygen depletion.

Brief Explanations:

Fertilizers can cause eutrophication. When they run - off into water bodies, they stimulate excessive growth of algae and other plants. When these plants die and decompose, oxygen is consumed, leading to oxygen depletion. Pesticides/herbicides can be harmful even after degradation, agricultural practices have significant environmental impacts, and tillage can cause soil erosion and other environmental problems.
