Eutrophication (Noun)
Meaning
Excessive nutrients in a lake or other body of water, usually caused by runoff of nutrients (animal waste, fertilizers, sewage) from the land, which causes a dense growth of plant life; the decomposition of the plants depletes the supply of oxygen, leading to the death of animal life; "he argued that the controlling factor in eutrophication is not nitrate but phosphate".
Classification
Nouns denoting natural processes.
Examples
- The excessive use of fertilizers in the nearby agricultural fields led to severe eutrophication in the lake, causing the death of many aquatic animals.
- Eutrophication in the river was evident from the thick layer of algae covering its surface, which was a result of the sewage and industrial waste being dumped into it.
- The controlling factor in eutrophication is not nitrate but phosphate, as it is the primary nutrient that promotes the growth of algae in water bodies.
- The rapid growth of aquatic plants due to eutrophication in the pond led to a significant decrease in the oxygen levels, making it difficult for the fish to survive.
- The government implemented strict regulations to prevent eutrophication in the lake by reducing the amount of nutrients entering the water body from the surrounding agricultural lands.
