Photosynthesis Plants use CO 2 from the atmosphere to make high-energy carbon molecules Back to the Carbon Cycle Metabolism Respiration Gas Exchange Pollution
Metabolism Organisms use high energy carbon molecules for growth Back to the Carbon Cycle Respiration Waste Decompositio n Photosynthesis
Respiration CO 2 is released through aerobic respiration (breathing, for example) Back to the Carbon Cycle Photosynthesis Metabolism Decompositio n
Waste Carbonates released into ground and water supply Back to the Carbon Cycle Gas Exchange Metabolism Photosynthesis Decomposition
Gas Exchange CO 2 is exchanged between the air and water Back to the Carbon Cycle PhotosynthesisWaste
Decomposition When organisms die and decay, the carbon molecules in them enter the soil. Microorganisms break down the molecules, releasing CO 2 Back to the Carbon Cycle Photosynthesis Pollution Metabolism
Pollution Remains of dead organisms are converted into fossil fuels (over millions of years!) Combustion of fossil fuels and wood releases CO 2 Back to the Carbon Cycle Using WaterMetabolism
Question 1: What would happen to primary producers and consumers if nitrogen-fixing bacteria were removed from the ecosystem?
Question 2: Grandma Johnson had very sentimental feelings toward Johnson Canyon, Utah, where she and her late husband had honeymooned long ago. Her feelings toward this spot were such that upon her death she requested to be buried under a creosote bush overlooking the canyon. Trace the path of a CARBON atom from Grandma Johnson’s remains to where it could become part of a hawk. Note: A hawk is a carnivore, but it did NOT dig up and consume Grandma Johnson’s remains!!!
