GEOLOGY

Detailed explanation-1: -Eutrophication is the process in which the water body becomes overly enriched with nutrients, leading to an increase in the production of algae and macrophytes. It deteriorates the water quality and depletes the dissolved oxygen of water bodies.

Detailed explanation-2: -The process of nutrient accumulation and enrichment of lakes is called eutrophication. This “aging” process is a natural process in the life of all freshwater lakes: all lakes, even the most pristine, will accumulate nutrients and sediments over long scale timeframes.

Detailed explanation-3: -WHAT HAPPENS WHEN THERE ARE EXCESSIVE NUTRIENTS? 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 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: -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.
