Question: 1 / 400

From the passage, what is noted about the ears of African desert foxes (fennecs)?

Their ears are small

Their ears help release body heat

The correct choice highlights the unique adaptation of African desert foxes’ ears, which play a significant role in thermoregulation. The large surface area of the ears allows for efficient heat dissipation, helping the foxes to maintain a stable body temperature in the extreme heat of their desert habitat. This ability to release body heat is crucial for their survival, as it enables them to stay active and hunt during the cooler parts of the day.

While the other options mention characteristics that might relate to the ear's size, hunting capabilities, or fur covering, they do not capture the key functional role that the ears play in helping these animals adapt to their environment. The adaptation of the ears for heat regulation is a fundamental aspect of the fennec fox's biology, enabling it to thrive where temperatures can soar.
