Answer Details

The phenomenon in the diagram shows an increase in the growth of algae and other aquatic plants due to an increase in nitrates in the water. One cause that could lead to this phenomenon is the dumping of sewage into the water bodies. Sewage contains high levels of nutrients, including nitrates, which when discharged into water bodies can cause an increase in the growth of algae and other aquatic plants. This increase in growth can lead to eutrophication, a process where the excessive growth of algae and other aquatic plants reduces oxygen levels in the water, leading to the death of aquatic organisms. Therefore, the dumping of sewage into water bodies can have serious negative impacts on the health of the ecosystem and human activities that depend on it.
