Carbon Cycle Note. Carbon Source: releases Carbon into atmosphere Human impacts Carbon Sink: reservoir that accumulates and stores Carbon Plants, oceans, and soil Organic Carbon: must be bound to Hydrogen Cellulose, CH4, Starches, Alcohols Inorganic Carbon: Carbon is not bound to Hydrogen
E N D
Carbon Source: releases Carbon into atmosphere • Human impacts • Carbon Sink: reservoir that accumulates and stores Carbon • Plants, oceans, and soil • Organic Carbon: must be bound to Hydrogen • Cellulose, CH4, Starches, Alcohols • Inorganic Carbon: Carbon is not bound to Hydrogen • Carbon Dioxide, Salts
Major Components • Plants take up lots of CO2 but release it when they die • Animals release CO2 when we breathe • Waste is considered a sink • Fossil Fuels were once long term sinks but are now major sources do to human consumption • Oceans deeper waters hold Carbon for a long period of time while shallow surface water would be a source due to the exchanges with other compounds
