2. Name the 5 basic needs of all organisms: Oxygen Food Water Living space Proper temperature

3. To change in order to make “fit” or suitable for an environment. What is adapting?

4. An ____________ is any body structure or behavior that helps an organism survive Two Types: structural & behavioral adaptation

5. Structural Adaptations: Physical characteristics that help an organism to survive.

6. Behavioral Adaptations: Activities performed by an organism to help it survive.

7. ____________________ is an adaptation where an animal can hide by blending in with its surroundings. Camouflage

8. Mimicry is an adaptation where one organism imitates another organism.

9. An instinct is a pattern of behavior that requires no thinking. Organisms know how to do this from birth.

10. Migration is an instinctive behavior in which some animals move from one place to another for a period of time.

11. Hibernation is an instinctive behavior in which some animals spend the winter in an inactive condition.

12. A learned behavior is a behavior that an animal learns through experience.

13. Is the adaptation structural or behavioral?

14. A polar bear’s fur

15. A bat eared fox’s big ears

16. Penguins huddling together to stay warm

17. A moth’s eyespots on its wings

18. Xylem in plants (tube that carries water to top of plant)

19. Geese flying south for the winter

20. A dormouse hibernating for the winter

21. Birds having hollow bones

22. Jacana birds build floating nests

23. A zebra’s stripes help it to hide

24. Sharp claws on a badger help it to dig

25. How do organisms survive when the ENVIRONMENT changes? As a population, they have to adapt…or else!

26. Natural Selection Over time, populations change naturally –Gradual process –No human involvement –Beneficial traits- become more common –Harmful traits- become less common (and eventually disappear)

27. Example: Forest trees have both orange and green beetles crawling on leaves. Birds flying over forest trees spot the orange beetles and eat them. The birds don’t eat the green beetles. Over time, orange beetles will eventually become extinct while the green beetles continue to survive and reproduce. Why didn’t the birds eat the green beetles? Which color trait was “beneficial” to have? Which color trait was “harmful” to have?

28. Selective Breeding Humans select specific organisms to breed together, in order to get certain “desirable” traits Humans control this process!!! –Often done by a professional breeder Types of animals are known as breeds, while types of plants are known as varieties Examples?
