Back

differences between organisms in the same species

Front

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.
• A new disease appears that infects the foxes.

Back

The air temperature significantly decreases in winter.
