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.
1. Define biogeochemical cycle. • THE CIRCULATION OF SUBSTANCES THROUGH LIVING ORGANISMS FROM OR TO THE LIVING ENVIRONMENT
2. What inorganic molecule is carbon normally found in? • CO2
3. Name an organic molecule that carbon is found in. • CARBOHYDRATES, LIPIDS, PROTEINS, NUCLEIC ACIDS
5. Where do primary consumers get their carbon from? • EATING PLANTS & PLANT-LIKE ORGANISMS
6. What process(es) add(s) carbon to the atmosphere? • CELLULAR RESPIRATION, COMBUSTION, DEATH & DECOMPOSITION
7. What process(es) remove(s) carbon from the atmosphere? • PHOTOSYNTHESIS
8. What substance do producers produce? • CARBOHYDRATES (GLUCOSE)
9. List 3 groups of producers? • PLANTS, ALGAE, & SOME BACTERIA
10. What is the name given to the group that eats producers? • PRIMARY CONSUMERS
11. Where do secondary consumers get their carbon from? • BY EATING PRIMARY CONSUMERS
12. Where do tertiary consumers get their carbon from? • BY EATING SECONDARY CONSUMERS
13. How does carbon get back into the atmosphere from the food we eat? • THROUGH CELLULAR RESPRATION
14. Where does an animal’s or plant’s carbon go when it dies? • THE GROUND OR ATMOSPHERE
15. Why should the amount of carbon in the atmosphere stay the same? • PHOTSYNTHESIS AND RESPIRATION SHOULD BALANCE EACH OTHER OUT.
16. How is EXTRA carbon getting into the atmosphere today? • BY BURNING FOSSIL FUELS
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.
18. How can excess CO2 be removed from the atmosphere? • PLANT TREES, CONSERVE ELECTRICITY, REMOVE CO2 FROM EMISSIONS, USE LESS FOSSIL FUELS
