Behaviour

Is an organism's response to changes in it's environment.

Behaviour can be inherited or learned.

Both genes and the environment influence your behaviour. 

For example, if a child is born deaf they don't hear people speaking so they don't learn to speak for a long period.

Some behaviour is inherited

Inherited behaviour is known as instinctive.

Animals will respond in the right way to a stimulus even if they have never done it before.

For example, new born mammals will suckle from their mothers without learning to.

They are automatic actions.
