Unit 3 Animal Adaptations Study Guide

Animal Adaptations Study Guide

Adaptation-  An adaptation is a physical feature (body part) or a behavior (the way an animal acts)  that helps it to survive.


Physical Adaptation-

Something on an animal’s body that helps it to survive in its habitat.

Examples are Camouflage, Mimicry


Camouflage - The color of an animal that allows it to blend in to its habitat.
Name two animals that use camouflage to protect themselves. ________________ and ___________________

Protection- An animal’s way of keeping itself safe from harm.
Can you think of one way an animal protects itself? _________________________________________________


Mimicry- An animal that copies the look of another animal.

What is one animal that we talked about in class that uses mimicry?  Hint- It copies the Monarch butterfly.


Behavioral Adaptation-

A way an animal acts that allows it to survive in its habitat.

Examples include Migration and Hibernation


Instinct- A behavior that an animal has that helps it meet its needs.


Learned Behavior-  A behavior that an animal acquires (learns to do) after birth.


Migration- The movement between habitats. Usually this movement is seasonal. Most animals migrate because it is becoming winter and their food supply is dying.  Can you think of an animal from our area that you’ve see migrating? Hint- you have to look up!


Hibernation - A state of rest that happens in some animals when the temperature outside becomes too cold.
Some animals can migrate when the seasons change so they hibernate instead.  They do this because the foods they eat often die in the winter. Can you name one animal that hibernates?


Extinct- When all of a species (kind of animal) is gone.

Endangered- When the population (number of) a kind of animals is few.

Habitat- The place where an animal lives.
One habitat might be a tree.


Ecosystem- Many habitats together.

An ecosystem might be the entire forest.


Population-  The number of a certain kind of living things living in an area.
The population of Madill is the number of people living in this town.  Animals have populations too. An animal population is the number of animals living in a certain habitat or ecosystem.


Think about it!


Question - Some animals like some bears, hibernate. What is the BEST explanation for this?

Answer- It is a winter survival technique. The food supply is scarce in the winter so animals go to “sleep’ so they don’t need to eat.


Question- Geese are birds that live in the north. They leave the north during the winter and fly to places that are warmer. After winter is over, they fly back to the north. What is this called?

Answer- Migration


Question- How is migration different than hibernation?

Answer- Migration is when animals move habitats, hibernation is when they become dormant but stay in one place.


Question- Review- What is the difference between cold-blooded and warm-blooded?

Answer- Warm blooded animals body temperature does not change when the environment gets hotter or colder.
