Exploring the Nitrogen Cycle Diagram & Questions A. Draw the nitrogen cycle including the 12 locations (atmosphere, dead plants and animals, animal waste, humans, live plants, live animals, surface water, ocean, groundwater, rainwater, fertilizer, soil) with the form of nitrogen and the arrows labeled with how the nitrogen traveled. Location: form of nitrogen Arrow: how nitrogen traveled B. Nitrogen cycle color coded Color code the diagram above as well as your created nitrogen cycle. Color 1dissolved nitrogen Color 2air nitrogen Color 3nitrogen in bodies as protein (amino acids) and nucleic acids (DNA, RNA) Color 4bacteria making nitrogen into usable form for plants/blue green bacteria C. Answer the following questions: 1. What macromolecules does the nitrogen cycle provide for you? Hint: CHON → CHOPN → 2. What role do bacteria play in the nitrogen cycle? 3. What role do plants play in the nitrogen cycle? 4. What role does lightning play in the nitrogen cycle? 5. The nitrogen cycle doesn’t have “balance issues” like the carbon cycle. Why not?
