The energy in food consumed by an organism is transferred to their body in the form of chemical energy. This chemical energy is then used by the organism to power their cellular processes such as metabolism, growth, and movement. During these processes, some of the chemical energy is converted into heat and released into the environment as waste. The rest of the energy is used by the organism to perform various activities required for their survival. Ultimately, the energy in food is either used by the organism or lost as heat.
