question 3 of 25
how does swimming in a large group help an individual fish survive?
a. it makes it more difficult for predators to catch an individual.
b. it prevents the individual from finding a mate.
c. it decreases the chances that the individual will be exposed to a
disease.
d. it makes it easier for an individual to compete for food.

Explanation:

When fish swim in a large group (shoal), the confusion effect occurs. Predators have a harder time singling out one fish. Options B is incorrect as group swimming doesn't prevent mating. Option C is wrong because a large group might increase disease exposure. Option D is false as competition for food might increase in a group.

Answer:

A. It makes it more difficult for predators to catch an individual.
