Best answer
Right option is (d) Heat

The best I can explain: During the flow of energy in an ecosystem, the energy is dissipated in the form of heat during several metabolic activities. Heat is a result of cell respiration, a form of energy that is not used in an ecosystem and released in an abiotic environment.
