Agricultural runoff
Correct Answer
A. Agricultural runoffExplanation
Artificial eutrophication or nutrient poisoning is primarily caused by excessive nutrients, such as nitrogen and phosphorus, entering water bodies. These nutrients can come from various sources, including agricultural runoff. When fertilizers and other agricultural chemicals are applied to fields, they can be washed away by rainwater or irrigation and end up in nearby streams, rivers, or lakes. This influx of nutrients can lead to an overgrowth of algae and other aquatic plants, disrupting the natural balance of the ecosystem and depleting oxygen levels in the water.Rate this question:
