What is natural selection?
Where organisms are in competition to see who can adpat and live the longest in their enviroment

Why is there variation in organisms?
The differences in their genes
2 of 6
Give an example of organisms who compete for resources?
A red squirrel has to compete with other red squirrels and grey squirrels in order to get food.
