Cultural eutrophication – predominantly due to increasing loads of nitrogen and phosphorus – leads to profound changes in the composition, biomass, and productivity of algae and plants. Eutrophication definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation. The cultural eutrophication process consists of a continuous increase in the contribution of nutrients, mainly nitrogen and phosphorus (organic load) until it exceeds the capacity of the water body (i.e. excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of … Learn more about it at BYJU'S. Cultural eutrophication occurs when human water pollution speeds up the aging process by introducing sewage, detergents, fertilizers, and other nutrient sources into the ecosystem. Cultural Eutrophication is the process that speeds up natural eutrophication because of human activity. Eutrophication alters the composition and diversity of aquatic plants, affecting ecosystem structure and the food web (Figure 5).Increased inputs can shift algal composition in a freshwater lake from diatom-dominated systems, typical of oligotrophic lakes, to blue-green algae-dominated systems.

Eutrophication is the emission of nutrients, mainly via water but also through the air, which find their way into other ecosystems and affect their relative growth patterns, posing a threat to biodiversity. ", Ocean pollution often results in _____ dead zones and _______ of toxic algae such as "red tide.". _____ treatment of water involves _________ bacteria in holding tanks. Cultural eutrophication causes excessive algal bloom in water bodies, with consequent algal overload. Bacteria and algae release toxins such as ______ ______ which decrease biodiversity and degrade water quality. A dead zone is a place where there is now concentration of dissolved oxygen. Fragile coastal marine ecosystems such as: coral reefs, grass flats, estuaries, and marshes are the most affected. Groundwater contamination is _____ and _______ to fix. It is created because of cultural eutrophication. Cultural appropriation occurs when a person from one cultural adopts the fashion, iconography, trends, or styles from another culture. Under certain conditions of darkness and warm temperatures these blooms may die, decompose and produce offensive sewage-like odor.
