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.
