Carbon Cycle

 Law of Conservation of Matter: Matter can NOT be created or destroyed, it changes form  Biogeochemical cycles: matter is constantly being cycled through changing form

 Bio = life  Geo = earth  Chemical= essential elements and compounds  H20= water  C= carbon  O=oxygen  N= nitrogen  CO2= carbon dioxide

 Cycle= move from beginning to end  Not always a beginning or end  Continuous  Biogeochemical Cycle: essential elements and compounds moving among living organisms (bio), the earth (geo) and atmosphere

 Carbon Cycle  ** Photosynthesis: process by which plants use the energy from sunlight to produce sugar  Sun + CO 2 + H 2 O C 6 H 12 O 2 (sugar)  Cellular Respiration: process by which cells harvest the energy stored in food  C 6 H 12 O 6 (sugar) CO 2 + H 2 O + energy

 Combustion: burning  Uses O 2  Releases CO 2  Decomposition: organisms breaking down into simple elements.
