In mammals and birds, the energy released from the oxidation of food is primarily used for maintaining body temperature, powering muscle contractions for movement, and supporting metabolic processes. This energy is derived from the breakdown of macronutrients like carbohydrates, fats, and proteins during cellular respiration. Additionally, birds and mammals utilize this energy to sustain high levels of activity and to support their endothermic (warm-blooded) physiological functions.
