Answer:
Eutrophic.
Step-by-step explanation:
Eutrophication is defined as the when natural water becomes overly enriched with nitrates and phosphates containing fertilizers, and detergents which induced excessive amount of algae in water. The process of eutrophication may result in water body oxygen depletion.
Example of eutrophication are algal bloom, and great increase of phytoplankton population which increased levels of nutrients in water body.
