Living organisms release energy gradually. why?

Answer:Living organisms release energy gradually to prevent most of the energy from heat loss. The cells release the chemical energy present in food and it should be utilized gradually to prevent the energy loss in the form of heat and light. Most of the energy released by the body is through cellular respiration. The energy is produced by the continuous process that occurs in the body, breakdown of food and energy production. If a huge amount of energy will be released from the body it will only be in the form of heat loss so to prevent the energy from lost in the form of heat living organism release energy gradually
