These green plants provide food and oxygen for other living things (consumers). Some consumers (herbivores) eat producers while some (carnivores) eat other consumers. Decomposers break down dead plant and animal materials into abiotic elements. Decomposers are recyclers; the abiotic elements return to the soil, water, and air for use again. This is how nutrients are cycled and recycled.
