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.
1. if a 68 {\rm kg} human used the same energy per {\rm kg} of body mass as a mouse, how much energy would be needed each day?
2. what resting power does this correspond to?
3. how much greater is this than the resting power noted in the chapter?
p = ?

Part 1)

E = 10200 Cal per day

Explanation:

Part 1)

Small mouse used the energy of 3 Cal

mass of the mouse = 20 g

so energy used per day per unit of mass is given as

Now for a person of mass 68 kg the energy is

per day

Part 2)

Resting power means the rate of energy consumed by the body while we are not doing any work and all that energy is consumed for several biological process.
