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

    11. Competition

    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
