Earth has four spheres the hydrosphere has to do with water. The lithosphere has to do with the soil/rock and the atmosphere has to do with air. Lastly the biosphere has to do with all living organisms.The biogeochemical cycles that occur in each sphere are the carbon cycle ,water cycle,nitrogen cycle and phosphorus cycle. Nitrogen is supplied by decomposers and it is removed by soil bacteria. Nitrogen is mainly added to feed plants.Carbon is released an removed from the atmosphere in many different ways,some being photosynthesis and the burning of fossil fuels. When carbon is in the form of carbon dioxide it is removed from the atmosphere through photosynthesis.Although the carbon cycle is extremely helpful it can be dangerous to marine life because it makes the ocean water acidic.Earths spheres are all connected because each one brings a different resource to life that we need to survive.The change in one sphere will ultimately affect at least one or more of the others.
