Answer:
Too many nutrients in water can cause algae to grow, which uses up the oxygen in the water. Fertilizers are rich in nitrogen and phosphorus which are source of nutrient pollution. These can enter the water bodies through surface runoff or during rain or contaminate ground water by leaching .
