Final answer:
Animals often migrate to more suitable habitats in response to temperature fluctuations. In this case, the animal at 20 degrees north latitude is likely to find suitable habitat by moving south.
Step-by-step explanation:
Animals often respond to temperature fluctuations by migrating to more suitable habitats. In this case, since the animal lives at 20 degrees north latitude, it is most likely to find suitable habitat by moving south of its current habitat. This is because as you move closer to the equator, the temperature generally gets warmer, providing a more favorable environment for the animal.
