Answer:
Algae as well as other plants naturally grow in water,but excess of these plants can be detrimental to organisms that live in water. In our homes and farms we use fertilizers to give our plants nutrients. Fertilizers contain nitrogen, phosphorus, and potassium. When it rains these fertilizers are washed off into the lakes,dams and rivers. These fertilizers accelerate the growth of algae, it grows uncontrollably across covering the lake. When the lake, dam or stream is covered with algae it blocks sunlight from entering the lake, thus plants under water cannot photosynthesize, thus oxygen is not created.
