Detailed explanation-1: -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-2: -Eutrophication is the process of increased productivity of a lake as it ages. Often this process is greatly accelerated by human influence and is termed cultural eutrophication. The increase in nutrient supply from human activities usually results in an increase in the biological production that occurs in the lake.

Detailed explanation-3: -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-4: -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.
