Explanation:
What I got to have
Eutrophication (from Greek eutrophos, "well-nourished") is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients. It has also been defined as a "nutrient-induced increase in phytoplankton productivity". Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication in freshwater ecosystems is almost always caused by excess phosphorus.
I hope this helps
Although the diagram is not provided, I have encountered it before. The region labelled "B" is a ring with two small particles on it. This ring is the electron cloud and is where the electrons move. Therefore, it is negatively charged.
