Solution Preview

Eutrophication occurs when an excess of nutrients, usually in the form of nitrogen or phosphorous, is released into a nutrient deficient water body (Cloern, 2007). This leads to an increase of aquatic plant growth. Over time, this excessive plant growth can turn the lake into a bog, with low oxygen content and life, or even into land. However, eutrophication is accelerated by human deposition of nutrients into a water body, which can create "dead lakes". Nutrients can be added to a water body artificially through fertilizer use, nutrients carried from runoff, agriculture, sewage treatment plants, suburban lawns, and dumping waste into the water system. ...
