Review of Animal Structures and Functions

Many nocturnal animals, each ear hears sounds separately from the other. This allows the animal to locate predators and prey all around it. Which statements describe the cupped part of an animal's ear AND how it affects hearing?

• The cupped part of an animal's ear is one part of the hearing system. A cupped ear catches more nearby sounds, which helps a nocturnal animal to hear better.

• The cupped part of an animal's ear is the whole hearing system. Cupped ears produce sounds that can travel long distances.

• The cupped part of an animal's ear is the whole hearing system. A cupped ear catches more nearby sounds, which helps a nocturnal animal to hear better.

• The cupped part of an animal's ear is one part of the hearing system. Cupped ears produce sounds that can travel long distances.

Nocturnal animals are active at night. These animals have a very good sense of hearing. Nocturnal animals often have special ears that help them hear better. Their ears are often shaped like cups. The drawing below shows the cupped ears of a nocturnal animal. Also, for many nocturnal animals, each ear hears sounds separately from the other. This allows the animal to locate predators and prey all around it. Which feature would BEST help a nocturnal animal survive at night?

• Having a poor sense of hearing

• Small, flat ears for hearing

• Relying only on sight to locate predators

• Hearing sounds separately in each ear

Animals have different structures that allow them to get information from their environment.
