change of season and fewer predators change of season and less food loss of habitat and fewer predators loss of habitat and more food
I gave my students this multiple choice question: Which two environmental changes usually cause certain animals to migrate?

Only one answer is correct among these 4 choices:
- change of season and fewer predators
- change of season and less food
- loss of habitat and fewer predators
- loss of habitat and more food

Could you tell me which one is correct?
