1. Warm-Up: Levels of an Ecosystem Label each descriptions as a population, community, or ecosystem. 1.Owls, mice, and grass all live in one area. 2.Owls, mice and grass all live in an area near a pond that receives lots of sunlight. 3.Eight owls all live in one area.

2. Animal Relationships & Adaptations

3. Niche =

4. Niche = organism’s role in an ecosystem

5. Relationships in an Ecosystem 3 types of relationships: predation competition symbiosis

6. Predation =

7. Predation = one organism is a food source for another organism Predator = hunter Prey = food

8. Competition =

9. Competition = struggle between organisms to survive in a habitat with limited resources

10. Competition limited resources = “Limiting Factors” Examples?

11. Competition largest population an environment can support = Carrying Capacity

12. Symbiosis =

13. Symbiosis = relationship between 2 organisms that benefits at least 1 of the organisms 3 types of symbiosis: mutualism commensalism parasitism

14. Mutualism = both organisms benefit

15. Commensalism = 1 organism benefits, other is not harmed

16. Parasitism = 1 organism benefits, other is harmed

17. Animal Adaptations 2 types: –Structural –Behavioral

18. Structural Adaptation = inherited physical characteristic Adaptation that an animal “HAS”

19. Structural Adaptation Escaping predators Examples?

20. Structural Adaptation Obtaining food Examples?

21. Structural Adaptation Reproducing Examples?

22. Behavioral Adaptation = inherited behavior Adaptation that an animal “DOES”

23. Behavioral Adaptation Camouflage = blending in with environment Examples?

24. Behavioral Adaptation Mimicry = acting like a different organism Examples?

25. Behavioral Adaptation Courtship = males & females of a species prepare for mating Examples?

26. Behavioral Adaptation Hibernation = greatly reduced body activity during winter Examples?

27. Behavioral Adaptation Migration = periodic journey of an animal from one place & back again Examples?

28. Instinct vs. Learning Instinct =

29. Instinct vs. Learning Instinct = behavior an animal can perform without being taught

30. Instinct vs. Learning Learning =

31. Instinct vs. Learning Learning = animal requires practice & experience to perform the behavior 4 types: conditioning trial-and-error insight imprinting

32. Conditioning = connecting a stimulus to a good or bad event

33. Trial-and-error = performing a behavior more skillfully with repeated practice

34. Insight = applying knowledge to solve a new problem

35. Imprinting = some newborn animals follow the first moving object they see
