Quiz on Natural Selection

What happens during natural selection?

• Organisms with no variations survive and reproduce more.

• Organisms that are better adapted to their environment survive and pass on their traits.

• All organisms have an equal chance of survival regardless of their traits.

• The environment adapts to the organisms living in it.

What is natural selection basically about?

• The process by which all organisms live longer and reproduce equally.

• The process by which organisms with variation compete worse and live shorter lives.

• The process by which organisms with variation help them survive in their environment, live longer, compete better, and reproduce more.

• The process by which organisms change their environment to suit their needs.

What does natural selection explain?

• How individual organisms change over their lifetime.

• How populations change as their environments change.

• How environments adapt to the populations living in them.

• How organisms can choose their traits.
