  • Keeping a Constant Body Temperature.
    • Much of the energy animals release from their food in cellular respiration is eventually transferred to their surroundings as heat.
      • Some of this heat is produced by the muscles as the animals move.
    • Energy transfers to the surroundings are particularly large in mammals and birds as they are warm blooded.
      • This is to ensure that they can keep themselves warm when it is cold and cool themselves down when it is warm.
        • They therefore need to eat a lot more than cold-blooded animals such as amphibians and fish to achieve the same increase in biomass.
