The biogeochemical cycles on Earth connect the energy and molecules on the planet into continuous loops that support life. The basic building blocks of life like water, oxygen, carbon, sulfur, nitrogen and phosphorous are recycled and go back into their respective cycles repeatedly. The biogeochemical cycles also create reservoirs of these building blocks such as the water stored in lakes and oceans and sulfur stored in rocks and minerals.
