Their numbers will increase. Their numbers will decrease. They will adapt new behaviors. They will migrate to new locations.
I gave my students this multiple choice question: In one area, a large source of prey for eagles is rabbits. If the number of rabbits suddenly decreases, what effect will it most likely have on the eagles?

Only one answer is correct among these 4 choices:
- Their numbers will increase.
- Their numbers will decrease.
- They will adapt new behaviors.
- They will migrate to new locations.

Could you tell me which one is correct?

Their numbers will decrease.
