• Their breathing slows.

• Their heart rate slows.

• They drink more during hibernation.

• They hibernate when the temperature is too cold.

• They hibernate when the temperature is too warm.

Which statement correctly explains how temperature affects animal growth?

• When temperatures are low, there is more food available, which means there will be less animal growth.

• When temperatures are low, there is less food available, which means there will be more animal growth.

• When temperatures are high, there is more food available, which means there will be more animal growth.

• When temperatures are high, there is less food available, which means there will be less animal growth.

How does temperature affect animals like the groundhog?

• Lower temperatures result in more food, so the groundhog stores body fat.

• Higher temperatures result in more food, so the groundhog hibernates.

• Lower temperatures result in less food, so the groundhog hibernates.

• Higher temperatures result in less food, so the groundhog migrates.

Temperature affects animal behaviors in various ways. Which of the following is NOT a way temperature influences animal behavior?

• Migration patterns

• Hibernation cycles

• Feeding habits

• Color of fur

Which statement explains how a change in precipitation could affect the animal population?

• An increase in rainfall would lead to more water for animals to drink, giving them more energy.

• A decrease in rainfall might cause plants to die, which means animals would have less food to eat.

• An increase in rainfall might cause landslides that would block animals from food sources, and they will die.

• A decrease in rainfall would cause smaller animals to move to places where larger animals could eat them.

How could flooding affect a bear’s ability to hibernate?

• Flooding could make it hard for the bear to leave the area to hibernate.

• Flooding could cause more plants to grow, allowing the bear to eat more food before hibernating.

• Flooding could bring warmer temperatures, which would give the bear more time to hibernate.

• Flooding could make it hard for the bear to find a safe place to hibernate.

Look at the bushes along the path. Why have they lost their leaves?

• They are hibernating because they are not making food.

• They are making food so that they can make new leaves.

• They are dormant because temperatures are low.

• They have died because they cannot make food.
