Life cycles recycle matter and to create balance on earth because
living organisms are dependent on other living organisms to survive
producers make their own food, consumers gain energy from producers, and decomposers break down dead matter into essential nutrients that are then reused by producers
producers gain energy from the sun, consumers gain energy from producers, and decomposers gain energy from dead consumers and recycle it back to producers
all of the above

Moreover, the biogeochemical cycles move through mainly the biotic and abiotic components of the earth, more elaborately the spheres -biospheres, lithosphere, hydrosphere and atmosphere regions of the ecosystem. These biogeochemical cycles, from its terminology and discernable word morphology- involves the biological, geological and chemical components that make out to complete an exact and purposed cycle. The purpose in these cycles are to maintain balance and to ensure the ongoing process of the living and non-living organisms in the environment. These cycles’ help to living organisms survive and thrive. One popular example is the water cycle.
