In a cold environment that supports life,an ectotherm is more likely to survive an extended period of food deprivation than would an equal size endotherm because the ectotherm
A)expends more energy per kilogram of body mass than does the endotherm.
B)invests less energy in temperature regulation.
C)metabolizes its stored energy more readily than does the endotherm.
D)has greater insulation on its body surface.

Question

Quizplus · Accepted Answer

Ectotherms invest less energy in temperature regulation than endotherms, which allows them to allocate more energy towards other processes such as metabolism and survival during periods of food deprivation. Endotherms, on the other hand, must constantly expend energy to maintain their internal body temperature even in cold environments, leaving them with less energy to allocate towards survival during food deprivation.
