Eutrophication can damage aquatic ecosystems by causing algal blooms, which can lead to oxygen depletion and the death of aquatic organisms.
Eutrophication occurs due to excess phosphorus and nitrogen, leading to algal blooms that block light and kill aquatic plants, causing oxygen depletion and the death of aquatic organisms. The rapid growth of algae and subsequent decay consume oxygen, resulting in dead zones with low oxygen levels, leading to fish kills and threatening aquatic life.
