Different types of Carbon• Carbon Dioxide Gas
• Dissolved Carbon dioxide
• Carbohydrates (e.g. glucose)
• Hydrogen carbonate ions (CO3-)
• Methane gas
• Peat – (organic C rich molecules)
• Hydrocarbons in oil and gas
• Corals and Molluscs
• Limestone Rocks (Carbonates)

Reservoirs and Processes
Reservoirs( places where carbon is stored)
• Living Plants
• Living Animals
• Decomposer organisms
• Soils and Organic molecules
• Fossil Fuels
• Sedimentary Rocks
• Corals and Shellfish
• Phytoplankton
• Oceanic Food webs
• Sea water
Processes(ways of moving carbon from one
reservoir to another)
• Photosynthesis
• Respiration
• Decomposition
• Diffusion
• Combustion
• Fossilization
• Feeding
• Erosion of rocks
• Volcanic eruption

Questions
1. Name three processes that release carbon dioxide into the atmosphere.
2. Name three process which move carbon from one reservoir to another, apart from to and from the atmosphere.
3. Describe the movement of carbon that would happen very quickly (in days) between two or more reservoirs. Include the reservoirs, the processes and the forms of carbon.
4. Draw a diagram and describe the movement of carbon though two or more reservoirs that would store carbon for thousands or millions of years.
5. A Carbon Sink is a reservoir which absorbs more carbon than it releases. Suggest two possible carbon sinks.
6. Carbon Flux is the flow of carbon from one reservoir to another and its rate is measured in Gigatonnes of Carbon per year (GtC/yr). Suggest the process which has the greatest carbon flux.

Questions
1. Outline the processes that release carbon dioxide into the atmosphere from the lithosphere (carbonate rocks).
2. Estimate the size of the Carbon Flux from the Biosphere to the Atmosphere which is caused by deforestation and the burning of wood. Give your answer in Gigatonnes of Carbon per year (GtC/yr) and explain how you made the estimate.

Carbon CycleA simple oceanic
food web.
Crustaceans and
Molluscs play an
important role in
the oceanic
carbon sink.

Questions
1. Explain the two main physical / chemical processes by which carbon dioxide molecules in the air move to the cells of phytoplankton in the ocean.
2. A Carbon Sink is a reservoir which absorbs more carbon than it releases. Suggest how carbon in the bodies of crustaceans and molluscs is removed from the oceanic food chain to become part of another, slower carbon reservoir.
