4 main carbon sinks |
Oceans, Sediments, Atmosphere, Biosphere |
|
Photosynthesis |
Carbon dioxide is removed from the atmosphere, and fixed as organic compounds (e.g. glucose) |
|
Feeding |
Method by which organic carbon is moved from one trophic level to the next in a food chain |
|
Respiration |
Metabolism of organic compounds for energy, with carbon dioxide being produced as a by-product |
|
Fossilisation |
Carbon from partially decomposed dead organisms becomes trapped in sediment as coal, oil and gas |
|
Combustion |
Burning of biomass/fossil fuels to produce heat and carbon dioxide |
|
Climate change poses a credible threat to the arctic |
Changing conditions in the arctic Rising sea levels Expansion of temperate species' ranges (competition for natives) Decomposition of detritus beneath the ice --> further enhance greenhouse effect Increased spread of pathogens Behavioural changes - algae bloom Loss of habitat Extinction of species |
