Question

Assuming that an animal generates heat at a rate proportional to its volume and can radiate heat at a rate proportional to its body surface area, which of the following would be best at maintaing its body temperature in a cold climate ?

Answer 1

Answer:

In a bear, the surface area is less as compared to volume. Thus, it Will generate more heat and radiate less making it suitable for living in cold climate.

Answer 2

Answer:

Many animals regulate their body temperature through behavior, such as seeking sun or shade or huddling together for warmth. Endotherms can alter metabolic heat production to maintain body temperature using both shivering and non-shivering thermogenesis
