Answer:
The right approach will be "Eutrophication".
Step-by-step explanation:
- The mechanism through which a reservoir, body of water, including stream is eutrophic, usually resulting from either the underlying and adjacent land's inorganic and organic overflow.
- Steadily increasing plants, as well as algae production that follows eutrophication, decreases the water is probably concentration of dissolved oxygen and induces other species to die prematurely off.
