Which of the following statements comparing endotherms and ectotherms is false?
A)Mitochondrial density and enzyme activity are 3-4 times higher in the cells of endotherms than in the cells of ectotherms of similar size.
B)Ectotherms can use more of their energy intake for reproduction than endotherms can.
C)Endotherms and ectotherms have about the same mass-specific metabolic rate.
D)Both endotherms and ectotherms exchange heat with the environment through convection,conduction,radiation,and evaporation.
E)The food requirements for ectotherms and endotherms are similar for organisms with similar body mass.

Question

While endotherms and ectotherms may differ in their overall metabolic rates, when accounting for size, their mass-specific metabolic rates tend to be similar. Statements A and B are both true: endotherms have higher mitochondrial density and enzyme activity, and ectotherms can allocate more energy towards reproduction. Statement D is also true as both types of animals exchange heat with the environment through convection, conduction, radiation, and evaporation. Statement E is not necessarily true, as the food requirements of an ectotherm may differ from an endotherm even if they have similar body mass, due to differences in metabolism and activity levels.
