Many species of fish live in groups known as shoals. Shoals of fish can live and travel together for part or all of their lives.
Which of the following best explains an advantage of populations of fish living in shoals?
A.
Shoaling has a survival advantage because it reduces competition over resources between individual fish of the same
species.
B.
Shoaling has a reproductive advantage because it increases the probability of inbreeding between closely related fish.
C. Shoaling has a survival advantage because it reduces the need for resources of individual fish within a population.
D.
Shoaling has a reproductive advantage because it increases the probability of an individual fish successfully finding a
mate of the same species.
