Detailed explanation-1: -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-2: -Eutrophication, is nutrient enrichment; it drives excess primary productivity in waterways. It can be either natural or caused by human impact.

Detailed explanation-3: -Eutrophication is a process of increasing biomass generation in a water body caused by increasing concentrations of plant nutrients, most commonly phosphate and nitrate.

Detailed explanation-4: -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-5: -Eutrophication is characterized by excessive plant and algal growth due to the increased availability of one or more limiting growth factors needed for photosynthesis (Schindler 2006), such as sunlight, carbon dioxide, and nutrient fertilizers.
