Based on how the metabolic rates of ectotherms and endotherms respond to temperature, at which temperature would you expect the differences in metabolic rates between ectotherms and endotherms to be largest? (Hint: Think about the response curve of each type of animal to environmental temperature.)

Question

Quizplus · Accepted Answer

Ectotherms have lower metabolic rates at lower temperatures, while endotherms maintain higher metabolic rates regardless of external temperatures. At 5°C, the difference is largest because ectotherms' metabolic rates are significantly reduced, while endotherms maintain their metabolic rates.
