only younger frogs will survive the number of predators will increase decrease in frog population as water evaporates increase in frog population as more land is exposed
I gave my students this multiple choice question: What is the most likely effect of a drought on a population of frogs that live in a shallow swamp?

Only one answer is correct among these 4 choices:
- only younger frogs will survive
- the number of predators will increase
- decrease in frog population as water evaporates
- increase in frog population as more land is exposed

Could you tell me which one is correct?

decrease in frog population as water evaporates
