Question:
Decreasing surface area to volume ratio helps reduce heat loss in colder climates. In which one or more of the following observations does this play a role?
Decreasing surface area to volume ratio helps reduce heat loss in colder climates. In which one or more of the following observations does this play a role?
Show Hint
When studying adaptations to cold environments, consider both physiological and behavioral strategies used by animals to maintain body heat.

- Related species of mammals are larger in size at higher latitudes.
- Birds lay more clutches of eggs at higher latitudes.
- Birds and mammals huddle tightly together at higher latitudes.
- Mammals have longer limbs and larger ears at higher latitudes.
Show Solution
Verified By Collegedunia
The Correct Option is A, C
Solution and Explanation
Step 1: Bergmann's Rule.
Larger body sizes at higher latitudes reduce the surface area to volume ratio, minimizing heat loss, as observed in mammals.
Step 2: Social Thermoregulation.
Birds and mammals huddle together to conserve heat in cold environments, effectively reducing their exposed surface area and thus heat loss.
