Quizplus · Accepted Answer

The energy source that powers the system is not directly used by consumers to make organic compounds. Rather, producers (e.g. plants) convert light energy to chemical energy, which is then passed on to consumers in the form of organic compounds. Consumers use the organic compounds they consume as a source of energy for their own metabolic processes.
