The Carbon Cycle: http://www.youtube.com/watch?v=U3SZKJVKRxQ http://www.youtube.com/watch?v=xFE9o-c_pKg Sun-provides energy as heat and light Carbonic acid in precipitation Attacks limestone in sea bedreturns CO2 into the water Attacks exposed limestonereturns CO2 to air Carbonic acid Earth Organic-made from diatoms(producers) and skeletons and shells of living organisms Inorganic made from calcium carbonate Carbon source refers to all the elements - organic or inorganic, which release carbon in some form into the atmosphere. Here are the sources: volcanic eruptions; respiration of animals and humans; decay of dead matter; combustion of fossil fuels; natural processes like conversion of limestone to lime( releases carbon dioxide), metamorphism of rocks; warm water bodies Carbon Sinks are anything that absorbs more carbon from the atmosphere than it returns and include plants, algae, and a few strains of bacteria (photosynthesis ) ; cold water bodies; landfills (artificial sink) Carbon Reservoirs store this element in various forms, for small or really long periods of time. They are: The Earth's atmosphere, which contains copious amount of CO2; organic elements like rocks (organic limestone); soil ; sediments; limestone and coal deposits; oceans which also contain a lot of dissolved carbon in various forms as well in the form of fossil fuels; volcanic eruptions and geothermal activities also release a lot of carbon into the atmosphere. Biotic: The living or once-living organisms in an ecosystem Abiotic: nonliving component of an ecosystem Q 1: Describe the form of carbon in the atmosphere. Q2: Describe the main sources of carbon on Earth. Q3: Explain why decomposers are so important to the cycling of carbon around the planet. Q4: Explain why plants are both consumers and producers of carbon. Refer to respiration and photosynthesis PHOTOSYNTHESIS: RESPIRATION: glucose + oxygen → carbon dioxide + water (+ energy) Q5: Explain how the environment is affected by humans continuing to burn fossil fuels. Q6: Coal, natural gas and oil consist mainly of carbon. Explain what a natural reservoir is. Q7: Identify where carbon moves through the abiotic and biotic components in this cycle. Q8: What key features make it a cycle? Name the three key components of the carbon cycle. What powers this cycle?
