Inv. 9.2: Natural Selection

Notes: Adaptations

Definition Adaptation- a characteristic that increases an organism’s ability to survive & reproduce A population adapts to its environment over time Adaptations arise through natural selection

3 Types 1.morphological adaptation- adaptive structure or body part - ex: long tongue of anteater helps in eating ants

2. physiological adaptation- adaptive cells & body systems - ex: platelets help blood clot 3 Types

3. behavioral adaptation- adaptive reactions to the environment - ex: mating dance of birds 3 Types

Create an Organism Pick one item and decide how an organism would use this appendage to help them survive either by (choose one!): finding food, hiding from predators, defending themselves or finding a mate In 10 minutes your group will share your organism’s –Name –Typical habitat –How it would use the appendage (arm, leg, mouth, tail…) –What is the purpose of the appendage
