Life and Biogeochemical Cycles

Life and Biogeochemical Cycles

Biogeochemical cycles refer to the cycles of water, oxygen, nitrogen and carbon dioxide. The movement and transformation of these elements and compounds between living organisms, the atmosphere, and the Earth's crust (lithosphere) are the components of these cycles. In the introductory event, you will choose different organisms to make up two food chains. In the experiment you will observe and compare water, oxygen, nitrogen and carbon dioxide cycles.
