| eutrophication |
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"

| eutrophication |
Eutrophication is the gradual increase and enrichment of an ecosystem by nutrients such as nitrogen and phosphorus. Although traditionally thought of as enrichment of aquatic systems by addition of fertilizers into lakes, bays, or other semi-enclosed waters (even slow-moving rivers), there is gathering evidence that terrestrial ecosystems are subject to similarly adverse impacts (APIS, 2005). ...

| eutrophication |
The slow aging process during which a lake, estuary, or bay evolves into a bog or marsh and eventually disappears. During the later stages of eutrophication the water body is choked by abundant plant life due to higher levels of nutritive compounds such as nitrogen and phosphorus. Human activities can accelerate the process.

| eutrophication |
Eutrophication refers to the accumulation of nutrients in a lake or landlocked body of water. This occurs naturally over many years but has recently been accelerated by fertilizer runoff from farms and sewage input. Algal blooms result and their decay removes dissolved oxygen, eliminating aerobic organisms such as fish, and may cause accumulation of sulphide in the water.

| eutrophication |
"Runaway" growth of aquatic plants that occurs when agricultural fertilizers containing phosphorus and nitrogen run off into lakes and ponds; also ultimately increases the plant death rate with the result that the bacterial decomposition of the dead plants uses up oxygen, causing ?h and other organisms to suffocate.
