When excess fertilization drains into a lake what may occur?

eutrophicationeutrophicationFertilizer in a lake helps algae grow. Up to a certain point, that is good. The algae turns carbon dioxide into oxygen and adds oxygen to the water. However, after that point, the algae covers the lake. Oxygen from the air can not get to deeper water. Dead algae falls to the bottom of the lake and decomposes. The process of decomposing uses up oxygen. The amount of oxygen in the lake drops below the point where fish can survive. Thus, over fertilization leads to a fish kill.
