  1. What’s an adaptation? • A structure or behavior that helps an organism survive in its environment.

  2. p 21 PART CHOICE AUTOMATIC BEHAVIORAL ADAPTATION STRUCTURAL ADAPTATION PHYSIOLOGICAL ADAPTATION Duck’s webbed feet Fish swim in schools You shiver when cold Dogs chase away strangers Monkey’s opposable thumb Wolf grows thick coat in winter Cats’ fur stands on end when threatened Birds fly south for winter Snake’s hinged jaw

  3. Adaptations Can you tell the difference between the 3 types? Structural, Behavioral, Physiological

  4. Example: fish swim in schools (protection)

  5. Example: bird calls (attract mates, defense)

  6. Example: squirrels bury nuts (resource for winter)

  7. burying food for winter swimming in schools calls or howls or cries Which type of adaptation? Structural - Behavioral - Physiological

  8. p 23 - action done on purpose to help with survival - by choice squirrels bury nuts (resource for winter)

  9. QUILLS on a porcupine (defense)

  10. prehensile tail on a spider monkey (for climbing)

  11. thick fur on an arctic fox (for warmth)

  12. QUILLS TAIL FUR Which type of adaptation? Behavioral - Structural - Physiological

  13. p 23 - physical feature that helps an organism survive - body part prehensile tail on a spider monkey (for climbing) - action done on purpose to help with survival - by choice squirrels bury nuts (resource for winter)

  14. Example: shedding winter coat (stay cool in hot weather)

  15. Example: sweating (stay cool)

  16. Example: adrenaline is pumped into the bloodstream when you get scared or surprised (heart speeds up – you’re ready to run)

  17. Example: your pupils automatically dilate (get bigger) in dark places, to let in more light normal pupil pupil in low light

  18. shedding fur in summer pupils change size to match the light adrenaline for speedy escape sweating to cool you Which type of adaptation? Behavioral - Structural - Physiological

  19. p 23 - physical feature that helps an organism survive - body part prehensile tail on a spider monkey (for climbing) - action done on purpose to help with survival - by choice squirrels bury nuts (resource for winter) - involuntary action or change - cell activity - automatic sweating to keep you cool
