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

2. There are 3 types: Structural Behavioral Physiological
Adaptations
There are 3 types:
Structural
Behavioral
Physiological

3. Structural Adaptations
Definition
Physical feature that helps and organism survive
Body part that gives an advantage

4. Structural Adaptation
Example: QUILLS on a porcupine (defense)

5. Structural Adaptation
Example: prehensile tail on a spider monkey (climbing)

6. Structural Adaptation
Example: thick fur on an arctic fox (warmth)

7. Structural Adaptations
Definition
Physical feature that helps and organism survive
Body part that gives an advantage
Example: QUILLS on a porcupine (defense)
Example: prehensile tail on a spider monkey (climbing)
Example: thick fur on an arctic fox (warmth)

8. Behavioral Adaptations
Definition
Things that organisms DO (voluntary)
A Way an Organism purposely acts to survive

9. Behavioral Adaptation
Example: fish swim in schools (protection)

10. Behavioral Adaptation
Example: bird calls (attract mates, defense)

11. Behavioral Adaptation
Example: squirrels bury nuts (resource for winter)

12. Behavioral Adaptations
Definition
Things that organisms DO (voluntary)
A Way an Organism purposely acts to survive
Example: fish swim in schools (protection)
Example: squirrels bury nuts (resource for winter)
Example: bird calls (attract mates, defense)

13. Physiological Adaptations
Definition
Chemical or cellular activity to help organism survive in its environment
automatic or involuntary

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

15. Physiological Adaptation
Example: sweating (stay cool)

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

17. Physiological Adaptations
Definition
Chemical or cellular activity to help organism survive in its environment
automatic / involuntary
Example: shedding winter coat (stay cool in hot weather)
Example: sweating (stay cool)
