Detailed explanation-1: -Eutrophication occurs when the water body becomes overly enriched with nutrients. It may lead to depletion of dissolved oxygen, decreased biodiversity, water intoxication and invasion of new species.

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: -An overabundance of nutrients-primarily nitrogen and phosphorus-in water starts a process called eutrophication. Algae feed on the nutrients, growing, spreading, and turning the water green. Algae blooms can smell bad, block sunlight, and even release toxins in some cases.

Detailed explanation-4: -Eutrophication occurs when a body of water receives an excessive nutrient load, particularly phosphorus and nitrogen. This often results in an overgrowth of algae. As the algae die and decompose, oxygen is depleted from the water, and this lack of oxygen in the water causes the death of aquatic animals, like fish.

Detailed explanation-5: -Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication can affect freshwater or salt water systems. In freshwater ecosystems it is almost always caused by excess phosphorus.
