Natural Selection Quiz

Which of these is an example of natural selection?

• The largest animal in a population will have more opportunities for reproduction.
• Several species of organisms work together so that they all succeed.
• One species takes all the resources in an environment leaving none for others.
• Organism that are best suited to an environment tend to survive and reproduce more often.

Which of the following explains adaptation.

• An individual organism changes to meet its needs in the environment. These changes pass down to their offspring.
• The species as a whole changes their characteristics.
• Beneficial traits allow organism to survive and pass on those traits
• New characteristics arise in a species as needed.  If these traits are helpful, they are passed down.
