NEET BIOLOGY

Detailed explanation-1: -Answer. A farmer applies excess fertilizer to one of her fields just before a rainstorm. The pollution is this most likely to lead to nutrient.

Detailed explanation-2: -Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae. Nutrients can run off of land in urban areas where lawn and garden fertilizers are used.

Detailed explanation-3: -Excess use of fertilizers causes environmental pollution as their residual and unused amounts will become pollutants for air, water and soil.

Detailed explanation-4: -Fertilization of surface waters (eutrophication) results in, for example, explosive growth of algae which causes disruptive changes to the biological equilibrium [including fish kills]. This is true both for inland waters (ditches, river, lakes) and coastal waters. Groundwater is being polluted mainly by nitrates.

Detailed explanation-5: -Fertilizers used in agriculture are a significant source of nutrient pollution to water. In fact, nitrogen and phosphorus runoff from agricultural fields are some of the largest sources of pollution to coastal “dead zones” across the United States.
