Lakes can be ______ to increase dissolved oxygen levels. It is created because of cultural eutrophication. The cultural eutrophication process consists of a continuous increase in the contribution of nutrients, mainly nitrogen and phosphorus (organic load) until it exceeds the capacity of the water body (i.e. Eutrophication alters the composition and diversity of aquatic plants, affecting ecosystem structure and the food web (Figure 5).Increased inputs can shift algal composition in a freshwater lake from diatom-dominated systems, typical of oligotrophic lakes, to blue-green algae-dominated systems.

The excessive algal growth came back three years later, causing problems to 500,000 residents of Toledo whose tap water was rendered hazardous to their health, when a toxic compound from the algae made its way into the city water supply. Step 4: Algae Dies And Is Decomposed By Bacteria Step 5: Decomposition Of Algae Increases Biological Oxygen Cultural eutrophication is when a flux of excess nutrients from human activity are added into a local run-off which in turns speeds up the natural eutrophication. toxicity at top of the food chain, water foul damage, degradation of water supply/infectious disease transfer, liver damage, brain damage, cancer, birth defects. Cultural eutrophication causes excessive algal bloom in water bodies, with consequent algal overload. Industrial agriculture, with its reliance on phosphate-rich fertilizers, is the primary source of excess phosphorus responsible for degrading lakes (Carpenter 2008). As per Wikipedia, “Eutrophication or more precisely hypertrophication, is the ecosystem’s response to the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.One example is the “bloom” or great increase of phytoplankton in a water body as a response to increased levels of nutrients.
