Eutrophication is a process in where there is an excess of salts and nutrients (mainly Nitrogen) in a body of water like a river or a lake. The algae growth is heavily increased because these organisms take advantage of the excess of nitrogen and spread around the body of water and in some cases fill the entire surface with organisms. The main consequence of this process is the loss of oxygen in the water.
