How Ecosystems Work Section 1 The Carbon Cycle Carbon stored in the bodies of organisms as fat oils or other molecules may be released into the soil or air when the organisms dies. A community is energyOrganisms in an ecosystem are tied together by the flow of energy from one organism to anotherThe food chain that exists when a herbivore eats a plant and a carnivore eats a herbivore depends on the energy entering the community in the form of sunlight. Food Chain Food chain shows one path of the flow of energy in an ecosystem Order of the food chain.
