Answer Details

The source of the nitrates in the diagram is fertilizers. Fertilizers contain nitrogen, which is an essential nutrient for plant growth. When fertilizers are applied in excess, the nitrogen can leach into the surrounding soil and eventually into nearby water bodies, leading to an increase in nitrate levels in the water. This excess nitrogen can cause an overgrowth of algae and other aquatic plants, leading to a decrease in oxygen levels in the water, which can harm fish and other aquatic life. Therefore, it is important to use fertilizers judiciously and avoid over-application to prevent nitrate pollution in water bodies.
