Why both a source and sink are necessary for converting heat into work ?

Assertion: The loss of biologically useful energy as heat with every energy transfer in a food chain is a consequence of the second law of thermodynamics. Reason: Energy does not remain trapped permanetly in any organism. It is either passed on to higher trophic level or becomes available to detritivores and decomposers after the organism dies.
