A recreational lake experiences eutrophication because of excess nutrients. Based on this information, how would the recreational lake most likely appear?

Answer: Murky and full of algae.

Explanation:

A lake is a body of water that is surrounded by land. There are millions of lakes in the world. Lakes vary greatly in size. Some are quite small enough to fit in your backyard. Small lakes are often referred to as ponds.

Eutrophication is the process by which lakes receive nutrients (phosphorus and nitrogen) and sediment watershed around causing it to become more fertile and shallow. This additional nutrients serves as food for algae and fish. Therefore, the more eutrophic a lake is, the higher the living organisms it sustains. When a lake becomes shallow from added sediments, more plants tend to grow because the littoral area which is the area of the lake that is more shallow for light to penetratrate through the bottom. This increases in overall percentage. Eutrophication is a process that occurs naturally that a lake goes through over hundreds to thousands of years. Natural eutrophication is also sometimes known as lake aging. Humans can speed up the process of eutrophication usually by adding excess nutrients and sediment to the lake causing the lake to change trophic states in a matter of decades. This eutrophication is known as cultural eutrophication because humans cause it.

In a nutshell, when a recreational lake undergo eutrophication, the appearance is murky and full of algae that derive food from the lake.
