In excessive amounts, however, nutrients cause a type of pollution called eutrophication.Eutrophication stimulates an explosive growth of algae (algal blooms) that depletes the water of oxygen when the the algae die and are eaten by bacteria.itrates and phosphates are nutrients that plants need to grow.
