Question

what is the most likely effect of a drought on a population of frogs that live in a shallow swamp?
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

Explanation:

Frogs in a shallow swamp rely on water. During a drought, water evaporates. This reduces their habitat and resources, leading to a decrease in population. Younger frogs are not more likely to survive specifically due to drought in this context. An increase in predators is not the most direct effect. And more land being exposed is not likely to increase the frog population as their main need is water.

Answer:

decrease in frog population as water evaporates
