C) lost in the form of heat as energy is passed up a food chain.
the first law of thermodynamics states that energy cannot be created or destroyed it can be changed from one form to another. It may occur when energy is transferred in a food chain. When one animal feeds The other animal, there is a loss of heat as energy in this process.
