Question
On a per-kilogram basis, why does a small mammal such as a shrew require so much more energy than does an elephant?
Step 1
This is represented by the equation: \[E = mc^2\] where \(E\) is the energy, \(m\) is the mass, and \(c\) is the specific heat capacity. Show more…

On a per-kilogram basis, why does a small mammal such as a shrew require so much more energy than does an elephant or other large mammal?
Larger animals use proportionately less energy than smaller animals; that is, it takes less energy per $\mathrm{kg}$ to power an elephant than to power a human. A 5000 kg African elephant requires about 70,000 Cal for basic needs for one day. a. If a 68 kg human required the same energy per $\mathrm{kg}$ of body mass as an elephant, how much energy would be required each day?
