Which of the Following Statements About Metabolic Rate is FALSE

Question

Which of the following statements about metabolic rate is FALSE?
A)The metabolic rate per gram of tissue is greater in large endotherms than in small endotherms.
B)The metabolic rate per gram of tissue is greater in endotherms than in ectotherms.
C)The metabolic rate per gram of tissue in ectotherms is dependent on external temperature.
D)Metabolic rate may be measured by determining the rate of oxygen consumption.
E)An organism's overall metabolic rate increases with the animal's mass.

Accepted Answer

The metabolic rate per gram of tissue is actually lower in large endotherms than in small endotherms, as larger animals have a lower surface-to-volume ratio and therefore lose heat less rapidly than smaller animals. However, overall metabolic rate is higher in larger animals due to their greater mass.
