What is meant by adaptations?
They are characteristics that lets an organism become successful and survive.
How can animals adapt to the winter?
Hibernation - sleeping through the winter
Migration - moving somewhere warmer. E.g birds
Growing thicker fur - keeping warm with thicker fur
What is interdependence?

What do species have in common?

Continuous variation - result in any value within a range. E.g height

What are genes?

What is natural selection?
Natural selection is the process of organisms evolving. Organisms with better adaptations will survive and reproduce having offspring that have similar adaptations.
