Explanation:
Detailed explanation-1: -Detergents and fertilizers contain phosphates as additives. The addition of phosphorus into water in the form of the phosphate anion (PO43−), encourage the formation of algae, which reduces the dissolved oxygen concentration of water. This process is known as eutrophication.
Detailed explanation-2: -Major sources of nitrate and phosphate are fertilizer, sewage and runoff from animal farms. Phosphate also comes from the erosion of phosphate-bearing soil and sediment during human land-altering activities such as construction and mining.
