fish in ponds fish in oceans plants in lakes plants in streams
I gave my students this multiple choice question: Warm water contains less dissolved oxygen than colder water. Which population will be most affected by a long period of hot, dry days?

Only one answer is correct among these 4 choices:
- fish in ponds
- fish in oceans
- plants in lakes
- plants in streams

Could you tell me which one is correct?
