Why Birds And Mammals Need Still More Energy?

Answer: They have to produce heat for keeping their body warm. Birds and mammals are warm-blooded animals that maintain a constant body temperature irrespective of their surrounding temperature.Jan 30, 2020[20]

Why Do Warm-Blooded Animals Use More Energy For Respiration?
