aquatic habitats of high productivity.

A lake or river that is enriched, or over-enriched, with nutrients, particularly nitrates or phosphates.

the state of a well-nourished, productive lake that typically exhibits low levels of dissolved oxygen.

Pertaining to a lake or other body of water characterized by large nutrient concentrations, resulting in high productivity of algae.

Describes an aquatic system with high nutrient concentrations. These nutrient concentrations fuel algal growth. This algae eventually dies and decomposes, with reduces the amount of dissolved oxygen in the water.

Water of high productivity.

Waters with a good supply of nutrients and hence a rich organic production (Gr. eu well, trophein to nourish).

a term that designates water enriched with a high quantity of nutrients resulting in a high growth of phytoplankton or seaweeds. The decaying of this plant matter sometimes results in the depletion of oxygen from the area, which can be toxic to other organisms.

A term applied to water that has a concentration of nutrients optimal, or nearly so, for plant or animal growth. In general, nitrogen and phosphorus compounds contribute to eutrophic conditions in coastal and inland fresh waters, respectively.

Having high levels of primary productivity or nutrients

the state of a water body when it has an excess of nutrients usually derived from agricultural fertilisers. The process by which a water body becomes overloaded with nutrients is known as eutrophication and leads to a dense plant population, the decomposition of which kills animal life by depriving it of oxygen.

yu-TRO-fik An aging lake, containing many nutrients and decaying organisms, often tinted green with algae. 880

Abundant in nutrients and having high rates of productivity frequently resulting in oxygen depletion below the surface layer of a water body.

lake classification used to describe bodies of water with high levels of nutrients in proportion to their volume of water.

Usually refers to a nutrient-enriched, highly productive body of water.

Waters rich in dissolved nutrients (especially nitrogen and phosphorus); leads to accelerated growth of algae and plants that depletes oxygen levels and reduces biodiversity

An environment rich in nutrient ions.

Water rich in mineral and organic nutrients that promote a proliferation of algae, which reduces the dissolved oxygen content.

Bodies of water or habitats that have a high concentration of nutrients, which is harmful to normal fish populations.

Rivers and lakes rich in organisms and organic material (eu = truly; trophic = nutritious).

A lake that has a high level of plant nutrients and biological productivity and a low oxygen content.

A term applied to water that has aconcentration of nutrients optimal, or nearly so, forplant or animal growth. In general, nitrogen andphosphorus compounds contribute to eutrophicconditions in coastal and inland fresh waters,respectively.

Eutrophic conditions occur when the concentration of nutrients in rivers, estuaries, and other bodies of water increases and results in anaerobic (lack of oxygen) conditions in the water column. The increase of nutrients stimulates algae "blooms" as the algae decays and dies, the availability of dissolved oxygen is reduced resulting in high BOD; as a result, creatures living in the water accustomed to aerobic conditions perish.

having excessive plant growth, such as algae, which kill animal life by depriving it of oxygen

Waterbodies characterized by high levels of nutrients (nitrogen and phosphorus)-often very productive system with many aquatic plants and algae.

Water that is high in nutrients and is highly productive.

rich in dissolved nutrients, often caused by pollution

Nutrient rich

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).

a body of water that is rich in dissolved nutrients, but can be deficient in oxygen.

Soils where the base saturation percentage is higher than 50%. They are high fertility soils.

highly fertile and nutrient enriched

Having optimal concentrations of nutrients (or nearly so) for plant or animal growth.

a body of water that is rich in nutrients, often resulting in a seasonal deficiency of dissolved oxygen

refers to a body of water which is excessively rich in dissolved nutrients and usually poor in dissolved oxygen. Opp: oligotrophic

have a high trophic status; usually applied to water bodies or to soil water with high concentrations of dissolved minerals, particularly phosphate.

from Greek for "well-nourished," it describes a lake with low water clarity and excessive plant growth due to high concentrations of nutrients.

Waters with a high concentration of nutrients and a high level of primary production.

Waters in which conditions are right for algae to maintain large populations and biovolumes, generally related to nutrient supply. Trophic state indicators above 50 are classified as eutrophic.

containing a high concentration of nutrients; particularly nitrogen and phosphorous

high in nutrients, with high organic production. Eutrophic lakes contain more phytoplankton (algae) than other lakes, and are common among more naturally fertile lowland regions in which human activity provides an increased supply of nutrients.

Reservoirs and lakes which are rich in nutrients and very productive in terms of aquatic animal and plant life.

Pertaining to a lake that has many nutrients, and therefore sustains many photosynthesizers. Eutrophic lakes often have abundant algal cover, cutting down visibility in the water.

Lakes: Shallow, murky bodies of water with concentrations of plant nutrients causing excessive production of algae.

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.

Containing an optimum concentration of plant nutrients.
