Eutrophication is the natural aging of a lake by nutrient enrichment of its water.

Vedclass · Answer

(D) Eutrophication is the natural aging of a lake by biological 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 begin to be deposited on the lake bottom. Over centuries,as silt and organic debris pile up,the lake grows shallower and warmer,with warm-water organisms supplanting those that thrive in a cold environment. Eventually,the lake becomes essentially a land mass.
