Water quality will improve. Aquatic animals will thrive. Fish will die from a lack of oxygen. Aquatic plants will stop growing.
I gave my students this multiple choice question: Which of these will most likely occur if chemicals from fertilizers run off into lakes and streams?

Only one answer is correct among these 4 choices:
- Water quality will improve.
- Aquatic animals will thrive.
- Fish will die from a lack of oxygen.
- Aquatic plants will stop growing.

Could you tell me which one is correct?
