Smaller mammals use proportionately more energy than larger mammals; that is, it

Question

Smaller mammals use proportionately more energy than larger mammals; that is, it takes more energy per gram to power a mouse than a human. A typical mouse has a mass of 20 g and, at rest, needs to consume 3.0 Cal each day for basic body processes.

A) If a 68 kg human used the same energy per kg of body mass as a mouse, how much energy would be needed each day? (I'm not sure which unit they require - either cal or J)

B) What resting power does this correspond to?

C) How much greater is this than the resting power noted in the chapter?

Explanation / Answer

A) Energy rate for mouse = Energy/ no of grams = 3.0cal/20g = 1.5cal/g

Energy needed per for human = mass*rate = 68*10^3 g*1.5cal/g = 10200 Cal

B) Resting power = Energy / time = 10200cal/day

C) Compare resting power given in the book and one from part B)
