Question

Transcribed Image Text:Kleiber's Law states that the metabolic needs (such as calorie
requirements) of a mammal are proportional to its body weight raised
to the 0.75 power.¹ Surprisingly, the daily diets of mammals conform
to this relation well. Assuming Kleiber's Law holds, answer the
following questions.
(a) Write a formula for C, daily calorie consumption, as a function of
body weight, W.
NOTE: Use k for the constant of proportionality.
C(W) =
(b) If a human weighing 150 pounds needs to consume 1800 calories
a day, estimate the daily calorie requirement of a horse weighing
740 lbs and of a rabbit weighing 11 lbs.
NOTE: Round your answers to the nearest calorie.
Daily calorie requirement of a horse =
Daily calorie requirement of a rabbit =
calories
Choose one
calories
(c) On a per-pound basis, which animal requires more calories:
a mouse or an elephant?
