The atmosphere. The biosphere (include fresh water systems and non-living organic material, such as soil carbon). The oceans ( including dissolved inorganic carbon and living and non-living marine biota). The lithosphere (sediments, Earth core including fossil fuels).
Carbon is released into the atmosphere in several ways Respiration by plants and animals. Decay of animal and plant matter. Combustion of organic material Production of cement. The ocean releases CO2 into the atmosphere. Volcanic eruptions and metamorphism
Carbon is taken from the atmosphere in several ways Photosynthesis. The oceans when the seawater becomes cooler, more CO 2 dissolve and become carbonic acid. In the upper ocean areas organisms convert reduced carbon to tissues, or carbonates.
Photosynthesis CO 2 + H 2 O + sunlight CH 2 O + O 2
Respiration CH 2 O + O 2 CO 2 + H 2 O + energy
Combustion or Oxidization of hydrocarbon CH O 2 CO H 2 O + energy
Human Impacts on the Carbon Cycle Burning fossil fuels have serious impact on the carbon cycle.
Fossil Fuel 86% of global primary energy consumption is fossil fuels.
