Study Notes
Biogeochemical Cycles
- The major biogeochemical cycles include water, carbon, nitrogen, oxygen, phosphorus, and sulfur cycles.
The Carbon Cycle
- In the carbon cycle, plants absorb carbon dioxide through a process called photosynthesis, where they convert CO2 and water into glucose and oxygen.
Biogeochemical Cycle Compartments
- The abiotic compartments of Earth in a biogeochemical cycle include the atmosphere, hydrosphere, geosphere, and cryosphere.
- The atmosphere is the layer of gases surrounding the Earth, holding gases such as nitrogen, oxygen, and carbon dioxide.
- The hydrosphere is the component of the Earth where water is found, including oceans, lakes, rivers, and groundwater.
- The geosphere includes the solid, rocky part of the Earth, including the crust and mantle.
- The cryosphere consists of the frozen parts of the Earth, including ice caps, glaciers, and sea ice.
