By adding bacteria to water. Negative environmental effects include hypoxia, the depletion of oxygen in the water, which may cause death to aquatic animals.”. due to runoff from the land, which causes a dense growth of plant life. Algae that feed on nutrients grow into unsightly scum on the water surface, decreasing recreational value and clogging water-intake pipes. When the algae die, bacteria that decompose the dead algae consumes even more dissolved oxygen, essentially suffocating other organisms, such as fish. The problem is intensified when these large collections of algae die and begin to decay. Therefore, a body of water that has undergone eutrophication is a 'well-nourished' lake. Agricultural fertilizers are one of the main human causes of eutrophication. You can recall this term by remembering that the word 'eutrophic' comes from the Greek language and means well-nourished. Other causes include sewage and aquaculture, which is the growing or farming of fish, shellfish and aquatic plants. As a result, it introduces high amounts of chemical nutrients therefore stimulating the dense growth of algal blooms and other aquatic plants which threatens survival of aquatic life in many ways. © copyright 2003-2021 Study.com. Why are nutrients from fertilizer harmful to aquatic ecosystems? The direct discharge of industrial waste water into water bodies presents similar outcomes.
