(A) Eutrophication is the natural aging of a lake by nutrient enrichment of its water. In a young lake,the water is cold and clear,supporting little life. With time,streams draining into the lake introduce nutrients such as nitrogen and phosphorus,which encourage the growth of aquatic organisms. As the lake's fertility increases,plant and animal life burgeons,and organic remains are deposited on the lake bottom. This process leads to high productivity in aquatic ecosystems.
