In a field study, scientists are comparing physical structures of fish from two different environments that are both geologically old, Lake A and Lake B. Lake A has the same habitat throughout and offers only a few food sources; Lake B includes many different habitats that present a variety of food sources. How are the two communities likely to compare in terms of how fish obtain nutrition?

Fish species in Lake A are more likely to exhibit adaptive radiation in feeding strategies.

Fish species in Lake B are more likely to show very diverse mouthparts than fish species in Lake A.

Fish species in Lake A are more likely to have very diverse mouthparts than fish species in Lake B, because of the greater competition between individuals in Lake A.

Fish species in both lakes are very likely to be endemic.
