Characteristic of waters rich in dissolved inorganic or mineral nutrient materials and exhibiting a paucity or complete lack of oxygen in the bottom waters as a consequence of high primary production and the high nutrient content
Having a large or excessive supply or plant nutrients, nitrates and phosphates, usually resulting in an increase in biomass and productivity, (see oligotrophic)
being rich in nutrients and minerals and therefore having an excessive growth of algae and thus a diminished oxygen content to the detriment of other organisms
a situation in which the increased availability of nutrients such as nitrate and phosphate stimulates the growth of plants such that the oxygen content is depleted and carbon sequestered
a (Gr ew, well; trophe, nourishment) the gradual increase in nutrients in a body of water Natural eutrophication is a gradual process, but human activities may greatly accelerate the process
Having concentrations of nutrients optimal, or nearly so, for plant, animal, or microbial growth (Said of nutrient or soil solutions and bodies of water ) The term literally means "self-feeding "
one of the four trophic state categories, the eutrophic state is defined as having a high level of biological productivity, second only to the hypereutrophic category The prefix "eu" means good or sufficient A eutrophic waterbody is capable of producing and supporting an abundance of living organisms (plants, fish, and wildlife)
the condition of water being rich in plant nutrients (Cole, 1994) Nutrient-enrichment causes biological productivity to increase, but biodiversity within the aquatic ecosystem to decrease In turn, eutrophic waters are also anaerobic (deprived of dissolved oxygen) Water is usually considered to be eutrophic if phosphorus loading exceeds 20mg/L
used to describe highly productive or enriched lakes and estuaries; generally lack diversity of species and have over abundance of algae or rooted plants and tolerant fish species, low dissolved oxygen levels, and high accumulation of soft bottom sediments
Having high concentrations of nutrients optimal, or nearly so, for plant or animal growth Can be applied to nutrient or soil solutions and bodies of water
