  1. Diagramming the Carbon Cycle Q&A Directions: Use pp. 350 & 352 to answer the following questions. If the information is not found on these pages, use the index of the book or a computer to research your answers.

  2. 1. Define biogeochemical cycle. • THE CIRCULATION OF SUBSTANCES THROUGH LIVING ORGANISMS FROM OR TO THE LIVING ENVIRONMENT

  3. 2. What inorganic molecule is carbon normally found in? • CO2

  4. 3. Name an organic molecule that carbon is found in. • CARBOHYDRATES, LIPIDS, PROTEINS, NUCLEIC ACIDS

  5. 4. What molecule do trees get their carbon from? • CO2

  6. 5. Where do primary consumers get their carbon from? • EATING PLANTS & PLANT-LIKE ORGANISMS

  7. 6. What process(es) add(s) carbon to the atmosphere? • CELLULAR RESPIRATION, COMBUSTION, DEATH & DECOMPOSITION

  8. 7. What process(es) remove(s) carbon from the atmosphere? • PHOTOSYNTHESIS

  9. 8. What substance do producers produce? • CARBOHYDRATES (GLUCOSE)

  10. 9. List 3 groups of producers? • PLANTS, ALGAE, & SOME BACTERIA

  11. 10. What is the name given to the group that eats producers? • PRIMARY CONSUMERS

  12. 11. Where do secondary consumers get their carbon from? • BY EATING PRIMARY CONSUMERS

  13. 12. Where do tertiary consumers get their carbon from? • BY EATING SECONDARY CONSUMERS

  14. 13. How does carbon get back into the atmosphere from the food we eat? • THROUGH CELLULAR RESPRATION

  15. 14. Where does an animal’s or plant’s carbon go when it dies? • THE GROUND OR ATMOSPHERE

  16. 15. Why should the amount of carbon in the atmosphere stay the same? • PHOTSYNTHESIS AND RESPIRATION SHOULD BALANCE EACH OTHER OUT.

  17. 16. How is EXTRA carbon getting into the atmosphere today? • BY BURNING FOSSIL FUELS

  18. 17. Some say we could reduce the extra carbon that is getting into the atmosphere by driving electric cars. What argument could you make against this idea? • MOST ELECTRICITY IS GENERATED BY COMBUSTING (BURNING) COAL.

  19. 18. How can excess CO2 be removed from the atmosphere? • PLANT TREES, CONSERVE ELECTRICITY, REMOVE CO2 FROM EMISSIONS, USE LESS FOSSIL FUELS
