Key piece of information

Carbon cycle Producers incorporate chemicals from the nonliving environment into organic compounds. Consumers feed on the producers, incorporating some of the chemicals into their own bodies and releasing some back to the environment in waste products. As organisms die, decomposers break them down, further supplying the soil, water, and air with chemicals in inorganic form. The producers gain a renewed supply of raw materials for building organic matter, and the cycles continue.
