What does the word eutrophication mean?
eutrophication, the gradual increase in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem such as a lake. The productivity or fertility of such an ecosystem naturally increases as the amount of organic material that can be broken down into nutrients increases.
When was eutrophication first discovered?
Eutrophication was recognized as a water pollution problem in European and North American lakes and reservoirs in the mid-20th century. Breakthrough research carried out at the Experimental Lakes Area (ELA) in Ontario, Canada in the 1970s provided the evidence that freshwater bodies are phosphorus-limited.
What is the history of eutrophication?
The term ‘eutrophication’ came into common usage from the 1940s onwards, when it was realized that, over a period of years, plant nutrients derived from industrial activity and agriculture had caused changes in water quality and the biological character of water bodies.

What is a good definition of cultural eutrophication?
In eutrophication. Cultural eutrophication occurs when human water pollution speeds up the aging process by introducing sewage, detergents, fertilizers, and other nutrient sources into the ecosystem.

How do you use eutrophication in a sentence?
Eutrophication in a Sentence ?
- The eutrophication process kills most animals in a body of water because all of the plants that grow there steal all of the oxygen.
- Eutrophication is caused when too much nutrient runoff gets into a body of water and causes rapid plant growth, depriving living organisms of oxygen.

What is Oligotrophic water?
Oligotrophic: An oligotrophic lake or water body is one which has a relatively low productivity due to the low nutrient content in the lake. The waters of these lakes are usually quite clear due to the limited growth of algae in the lake. The waters of such lakes are of high-drinking quality.
What is eutrophication and where does it come from?
Eutrophication Has Greek Roots. Eutrophication, which comes from the Greek eutrophos, “well-nourished”, has become a major environmental problem. Nitrates and phosphates, especially from lawn fertilizers, run off the land into rivers and lakes, promoting the growth of algae and other plant life, which take oxygen from the water,…
How do fertilizers cause eutrophication?
When introduced to an aqueous ecosystem, the fertilizers supply plentiful nutrients to algae and plankton, resulting in the eutrophication of the water body. Overpopulation places a huge demand on industrial and agricultural expansion, which in turn leads to deforestation.
What are the adverse effects of eutrophication on aquatic bodies?
Primarily, the adverse effects of eutrophication on aquatic bodies include a decrease in biodiversity, increase in toxicity of the water body, and change in species dominance. Some other important effects of this process are listed below.
Which form of nitrogen is most often of concern for eutrophication?
Chemical forms of nitrogen are most often of concern with regard to eutrophication, because plants have high nitrogen requirements so that additions of nitrogen compounds will stimulate plant growth.
