Explanation:

Eutrophication is the process where excessive nutrients, primarily nitrogen and phosphorus, enter a body of water. This leads to a chain of events:

1. Nutrient Enrichment: Fertilizers, sewage, and industrial runoff contribute to elevated nutrient levels in lakes and rivers.
2. Algae Bloom: The increased nutrients fuel rapid growth of algae and other aquatic plants, resulting in a dense bloom.
3. Reduced Sunlight Penetration: The dense algal bloom blocks sunlight from reaching the lower depths of the water body.
4. Aquatic Plant Death: Lack of sunlight inhibits the growth of submerged aquatic plants, leading to their death and decay.
5. Decomposition by Bacteria: Bacteria decompose the dead plants, consuming large amounts of dissolved oxygen in the process.
6. Oxygen Depletion (Hypoxia/Anoxia): This oxygen depletion creates hypoxic (low-oxygen) or anoxic (no-oxygen) conditions in the water.
7. Fish Kills & Ecosystem Collapse: Fish and other aquatic organisms cannot survive in low-oxygen environments, leading to fish kills and a collapse of the aquatic ecosystem.
8. Dead Zones: Severe eutrophication can result in the formation of dead zones, large areas of water with very low or no oxygen, incapable of supporting most life.
