Detailed explanation-1: -Eutrophication is the process by which a body of water becomes enriched in dissolved nutrients (as phosphates), stimulating the growth of aquatic plant life usually resulting in the depletion of dissolved oxygen.
Detailed explanation-2: -Harmful algal blooms, dead zones, and fish kills are the results of a process called eutrophication-which occurs when the environment becomes enriched with nutrients, increasing the amount of plant and algae growth to estuaries and coastal waters.
Detailed explanation-3: -Eutrophication is a natural process that results from accumulation of nutrients in lakes or other bodies of water. Algae that feed on nutrients grow into unsightly scum on the water surface, decreasing recreational value and clogging water-intake pipes.
Detailed explanation-4: -Eutrophication of lakes is caused by overenrichment with nutrients, principally phosphorus (5). Excess phosphorus inputs to lakes usually come from sewage, industrial discharges, and runoff from agriculture, construction sites, and urban areas.
Detailed explanation-5: -Definition: Eutrophication is a process in which nutrient-rich water bodies support a dense plant population that kills animal life by depriving it of oxygen, resulting in biodiversity loss.
