  3. Computer Model for Seasons and Disturbances Read the handout until Section A to review the Constant Flux and Changing Fluxes Simulations. What did you learn from the first two simulations? How is Model 3 different?

  4. The Seasons Model 3 without seasonal variation • Carrying capacity = 90 kg/yr • Atmospheric pool = 500 kg • Organic carbon pool = 500 kg

  5. Question 1

  6. The Seasons Model 3 with seasonal variation • Carrying capacity = 90 kg/yr • Atmospheric pool = 500 kg • Organic carbon pool = 500 kg

  7. Question 2

  8. Question 3

  9. Press and Pulse Disturbances

  10. Disturbances in Real Ecosystems Read about disturbances in real ecosystems. What are some examples of press and pulse disturbances? Record your answer for Question 6 on your worksheet.

  11. Discussion • How do the pools and fluxes change during seasons? Why? • How do disturbances affect ecosystems?
