Use the diagram above that shows the effect of nitrates on water bodies Study it carefully and answer questions. The phenomenon in the diagram is termed

The phenomenon in the diagram is eutrophication. Eutrophication is a process that occurs when excessive nutrients, such as nitrates, are added to a water body. These nutrients promote the growth of algae and other aquatic plants, which can lead to an increase in organic matter in the water. As the organic matter decomposes, it consumes oxygen, which can lead to hypoxia (low oxygen levels) in the water. This can be harmful to fish and other aquatic life, and can even lead to the death of these organisms. Therefore, eutrophication can have negative impacts on aquatic ecosystems and water quality.
