Question 2

Explain what causes a lake to become a eutrophic lake, how this impacts biological productivity, and how that leads the end fate of a lake.

Accepted Answer

Eutrophic lakes have been filling with sediments that allow them to become more shallow. In turn, this type of  lake becomes more shallow and allows more sunlight to reach the bottom of the lake. In turn, more biological productivity occurs allowing for a higher concentration of nutrients to exist in the lake. Ultimately, the lake will fill  up with sediment and no longer be a lake.
