Questions: How Seasons Affect Animals

Question 1

Why do some birds fly to warmer places in autumn and return in spring?

• A. They get bored in one place and like to travel
• B. The cold weather directly hurts them, so they must leave
• C. Their food (like insects and seeds) becomes scarce in winter, so they fly to places where food is still available
• D. Other animals chase them away

Answer: (C)

Migration is mainly about food, not just cold. Many birds eat insects or specific plants that disappear in winter. By flying to warmer places where food is still available, they can keep eating and surviving. When spring returns and food becomes available again in their home area, they fly back to raise their young.

Question 2

Hibernation is the same as regular sleep -- the animal just sleeps longer than usual.

• T. True
• F. False

Answer: False

Hibernation is very different from sleep. During hibernation, an animal's heart rate drops dramatically (a bear's might go from 40 beats per minute to just 8), body temperature falls, and breathing slows way down. The animal is in such a deep state that it is hard to wake up. This extreme slowdown lets the animal survive for months without eating, burning stored body fat very slowly.

Question 3

Besides migrating or hibernating, what is one other way an animal might survive the winter?

Model answer: Some animals stay active but adapt. For example, squirrels gather and store nuts before winter so they have food. Rabbits and foxes grow thicker fur to stay warm. Some animals, like the Arctic hare, change their fur color to white to blend in with the snow. These adaptations help them survive cold temperatures and find food.

Not all animals migrate or hibernate. Many stay and cope by changing their bodies or behaviors. Understanding the variety of survival strategies shows that there is no single right way to deal with seasonal change.
