I gave my students this multiple choice question: Which event would most likely result in more food for organisms that are scavengers?

Only one answer is correct among these 4 choices:
- Fish die and sink to the bottom of a pond.
- Trees take up and store water with roots.
- Beavers build a new dam and lodge.
- Plants get more sunshine and water.

Could you tell me which one is correct?
