NO LABS NEXT WEEK, work on Water Footprint due on ANGEL on Friday, September 6-need data for this week and next week, so start now IV. POGIL 2.1: The Carbon Cycle1. Figure 2.1.2 in e-text describes the Carbon Cycle, KNOW the stocks and flows of all the components.2. Carbon in the surface waters of the ocean includes dissolved gaseous carbon and carbon in bodies of _______.-organisms3. List the stocks of carbon in the order of magnitude from largest to smallest. (You may combine dissolved gaseous carbon and carbon in organisms as one stock in the surface water).-OFRSAP(ocean>fossil fuels>reactive sediments>soil>atmosphere>plants)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.4. The flows of carbon between stocks operate at very different time scales. What is an example of a flow that would happen quickly? ______ What is an example of flow that would happen very slowly? ______-photosynthesis, fossilization5. Fill in the chemical equation of photosynthesis.-CO2+H2O->sugar+O26. The laws of thermodynamics state that energy cannot be created or destroyed; it may only change forms. If the energy from sunlight is used for photosynthesis, where does the energy go?-stored in carbon bonds7. Fill in the chemical equation for respiration.-sugar+O2->CO2+H2O+energy8. The laws of thermodynamics state that energy cannot be created or destroyed; it may only change forms. If the energy from food is released through respirations, where does the energy go? (What do organisms use it for?)-moving, breathing, eating, etc.9. Plant and animal material that becomes fossilized into rocks is _____.-coal Plant and animal material that becomes fossilized into liquid is _____.-petroleum Plant and animal material that becomes fossilized into gas is ______.-natural gas10. Where is the energy stored in the fuels described in #9?-carbon bonds11. Fill in the chemical equation for combustion.-carbon fuel+oxygen->CO2+H2O+energy12. The laws of thermodynamics state that energy cannot be created or destroyed; it may only change forms. If the energy from fossil fuels is released through combustion, where does the energy go?-makes the car go13. #8 and #12 asked what happens to released energy. What are two things that your answers have in common?-they both make something go14. There are carbon atoms in the bone in your arm. Where did that carbon come from?-carbon in air>photosynthesis>we eat it Where did the energy in the carbon bonds that hold your bones together come from?-respiration15. In a few grammatically correct sentences, specifically describe the importance of carbon to life as we know it.-own interpretation of carbon as the “duck tape of life”16. In a few grammatically correct sentences, explain in your own words that how having more molecules of in CO2, the atmosphere increases the capacity of the atmosphere to hold heat.-CO2 molecules absorbs heat energy and vibrates and transfers its energy and then absorbs more17. What was the atmospheric concentration of CO2 in 1955 and in 2008?-1955: 315ppm-2008: 385ppm18. What change in the carbon cycle is causing the increase in atmospheric CO2? What carbon stock is flowing into the atmosphere? What process creates this flow?-Combustion19. The Mauna Loa Observatory graph illustrates a measured increase in atmospheric CO2 that has a sawtooth shape. What processes creates this behavior?-Northern hemisphere=more plant biomass, seasons changing=release in CO2 back in the
