Biogeochemical Cycle

What is Biogeochemical Cycle? The biogeochemical cycle may be defined as the more or less circular path which brings about the circulation of chemicals and elements, including all essential elements from the environment to the organisms and back to the environment. Types of Biogeochemical Cycle: Gaseous Cycles: In which the reservoir is in the atmosphere. For example- carbon, hydrogen, oxygen, and nitrogen cycles. Sedimentary Cycles: In which the reservoir is in the lithosphere. For example- phosphorous, sulfur and calcium cycles. Why are biogeochemical cycles essential to long-term life on Earth? Biogeochemical Cycles are essential to long-term, sustainable life on Earth … Continue reading Biogeochemical Cycle
