Inherited and LearnedBehaviors

Traits (Behavior)• Traits are something an organism does.

• Examples:

A bear hibernating

Plant stems growing up and roots growing down

Inherited Traits

• Migration-seasonal movement of animals from one place to another

• Protecting Young

• Walking

• Eating

• Breathing

Learned Behavior

• A learned behavior is a behavior that an animal develops by observing other animals or by being taught.

• Birds avoiding viceroy butterflies

Learned and Inherited

• Some behaviors animals have are a combination of learned and inherited traits.

• Examples:Young cheetahs have the instinct to hunt,

but at first do not know how to sneak up on their prey. They learn how to do that by watching their mother when she hunts.

Wolves have the instinct to hunt but learn to hunt in groups.

Hunting in Packs

Plant’s Behavior

• All plant behavior is inherited (they can’t learn can they?).

• However, plants will respond to their environment.

Plants responding to their environment

• A plant’s response to a stimulus is called tropism.

• If you put a plant near a window it will turn it’s leaves toward the sunlight.

• Plants roots grow downward toward water.
