Chapter 10.A, Problem 75E
Squirrels or People? Squirrels and humans are both mammals that stay warm through metabolism that takes place in the body volume. Mammals must constantly generate internal heat to replace the heat that they lose through the surface area of their skin
- In general terms, how does the surface-area-to-volume ratio of a squirrel compare to that of a human being?
- Which animal must maintain a higher rate of metabolism to replace the heat lost through the skin: squirrels or humans? Based on your answer, which animal would you expect to eat more food in proportion to its body weight each day? Explain.
