Term used to describe the productivity of the lake ecosystem and classify it as oligotrophic (low productivity, "good" water quality), mesotrophic (moderate productivity), or eutrophic (high productivity; "poor" water quality).
The degree of fertility of a lake. Factors used to assess the trophic state of a lake include chlorophyll , dissolved oxygen and phosphorus concentrations. algal biomass, Secchi depth and macrophyte biomass. See also hyper-eutrophic lakes, eutrophic lakes, mesotrophic lakes. oligotrophic lakes, dystrophic lakes.[Gk. trophe, nourishment.
the degree of biological productivity of a waterbody. Biological productivity generally relates to the amount of algae, aquatic plants, fish and wildlife a waterbody can produce and sustain.
The nutrient level of a body of water. There are 3 levels: Eutrophic (high in nutrients), Mesotrophic, and Oligotrophic (low in nutrients).
the extent or condition of eutrophication in a body of water.
The measure of a lake's fertility resulting from the quantities of the nutrients nitrogen and phosphorus in its water.
Eutrophication is the process by which lakes are enriched with nutrients, increasing the production of rooted aquatic plants and algae. The extent to which this process has occurred is reflected in a lake's trophic classification or state: oligotrophic (nutrient poor), mesotrophic (moderately productive), and eutrophic (very productive and fertile).
