Eutrophication is a process in which excessive nutrient inputs (primarily nitrogen and phosphorus) in water bodies lead to an overgrowth of algae and other aquatic plants. This overgrowth can reduce oxygen levels in the water, leading to the death of fish and other aquatic organisms. Oil spills, acid rain, and industrial discharge can also contribute to water pollution, but they are not the primary cause of eutrophication.
