15. Explain how the size of these animals' ears can help the animals survive in their environment.

In addition to their use for hearing, ears contain many blood vessels that allow heat to escape into the
air. Animals that live in warm climates tend to have ears with large areas exposed to the environment.
Animals in cold climates have a more compact ear that keeps exposure to the environment to a
minimum. The photographs below show a jackrabbit from desert regions of the southwestern United
States and a fennec fox from northern Africa with large ears, and a snowshoe hare and an arctic fox with
small ears.
