Question

A new predator Is Introduced to an aquatic ecosystem. In a population of fish that live there, very small fish

are more easily able to hide from the predators, and very large fish cannot be easily eaten by predators.
What type of natural selection is acting on the population, and what will be the expected result?
O Disruptive selection: Over time the fish population will change. Medium-sized fish will become rare, small
and large fish will be common.
O Stabilizing selection: Over time the fish population will change. Medium-sized fish will become rare, small
and large fish will be common.
O Disruptive selection: Since both extremes are selected against, the fish population will remain about the
same.
Stabilizing selection: Since both extremes are selected against, the fish population will remain about the
same.
