Biology Jan 26 *Carbon Cycle Sources of Carbon Living Things- All living organisms have a carbon framework CO2-entire bases of life; only .3% in our atmosphere. 78% nitrogen 21% oxygen CO2+H2O+engery/chlorophyll = glucose= carbs, proteins, fats, nucleic acid Respiration -glucose+o2= ENGERY and CO2+H2O Minerals Carbonates (limestone, Hokie Stone) Fossil Fuels Additions to the Atmosphere- increase CO2 Respiration Industrial Pollution, from fossil fuels Erosion of minerals- limestone can dissolve *Nitrogen Cycle 78% of atmosphere is Nitrogen Importance to Living Things -Amino Acids -Component of Proteins and other Biological molecules -Aids in growth of plants; is in fertilizer Addition to the atmosphere -Nitrogen Fixation from Bacteria *Starts from legumes, soybeans, peanuts *Incorporated into Amino Acids and Protein -Erosion from minerals -Run off from fertilizers -Lightening and formation of nitrates -Industrial Pollution
