What accounts for the differences in metabolic rates of animals?

Question

Quizplus · Accepted Answer

The metabolic rate of an animal is influenced by various factors, including body size, activity level, and temperature. Body size can have a significant impact on metabolism, as larger animals require more energy to maintain their activities and vital functions than smaller animals. Activity level also plays a role, as animals that are more active require more energy than sedentary animals. Temperature can affect metabolic rate through its impact on enzyme activity and other physiological processes. Therefore, all of the above factors can contribute to differences in metabolic rates among animals.
