Why do birds and mammals need more energy?


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.

  • Warm-blooded animals such as birds and mammals maintain constant body temperature by cooling themselves when they are in a hotter environment and warming their bodies when they are in a cooler environment.
  • Hence, these animals require more oxygen (O2) for more cellular respiration to produce more energy to maintain their body temperature.
