Question

All of these are reasons why some small fish group themselves together in schools EXCEPTA)to conserve energyB)to locate food easierC)to stay cooler in warm waterD)to protect themselves from predators

Answer 1

Fish group in schools because it provides benefits such as protection from predators, conservation of energy while swimming, and a more effective search for food. However, staying cooler is NOT a benefit derived from being in a school, because a group of organisms have a higher temperature than the individual.

This means the right answer is C, stay cooler in warm water is not a reason for fish to form schools.
