The term "thermogenesis" is used in the context of production of heat within organisms like animals or humans. Thermogenesis can also occur in plants. More information can be found in the related Wikipedia article entitled "Thermogenesis".

10% of energy is used in Diet-Induced thermogenesis (DIT)

Thermogenesis

Adaptive Thermogenesis: This can be defined as the regulated production of heat in response to environmental changes in temperature and diet, resulting in metabolic inefficiency. For example, shivering when we are cold uses energy and this is an example of adaptive thermogenesis. (Alexander Bowring 24 / 04 / 2008)
