A fox with thicker fur than average would have a survival advantage over other foxes if:

• There is more competition for food in the fox population.

• The air temperature significantly decreases in winter.

• A drought occurs, limiting the amount of water available.

The fur of the snowshoe rabbit changes to a lighter color in the winter. This allows the rabbit to blend in with its surroundings. This change is an example of:

• Competition

• Succession

Animals may fight, make threatening sounds,and act aggressively toward members of the same species. These behaviors usually occur as the result of:

• Adaptation

• Evolution

• Competition

• Variation

The finches on the Galapagos island were similar in form except for variations of their beaks. Darwin observed that these variations were useful for:
