Literally meaning: “well-nourished”
Origin: Anc Greek
+ τροφή/trophe(=food, nourishment )
In 1919 Swedish limnologist Einar Christian Leonard Naumann (1891-1934) introduced into limnology the concepts of oligotrophy (nutrient poor) and eutrophy (nutrient rich).
Eutrophication is the process by which an aquatic ecosystem (body of water) is getting rich with inorganic plant nutrients (e.g. nitrate, phosphate) promoting algal blooms which use up all the oxygen in the water, leaving none for other aquatic organisms like fishes.
