Question

what will most likely happen to a population when the availability of food and water is less than what a given population needs?○ emigration○ large immigration○ no change○ small immigration

Explanation:

When a population's food and water needs are not met, individuals will leave the area to seek sufficient resources, which is emigration. Immigration (large or small) would involve individuals entering the area, which is unlikely when resources are scarce, and no change is not plausible as resource limitation impacts population movement.

Answer:

emigration
