Section 1: The Moose Arrive 

Be sure to answer the questions in the simulation as you complete this section. You will not necessarily lose points even if you answered the simulation questions incorrectly, however, you will be deducted points if any questions are not attempted. 1. Explain in your own words the difference between a stable population size and the maximum

population size. Which one is associated with carrying capacity?

2. What aspect of the habitat do you believe to be limiting the moose population by the time it hits carrying capacity?

3. Provide a brief summary of what you learned about how carrying capacity and resource limitations relate to logistic growth.

Section 2: The Wolves Arrive 

1. In this section, you were asked to provide a hypothesis of what will happen to the moose population after the introduction of wolves to the island. Provide your hypothesis below and explain your reasoning behind selecting this hypothesis.

2. Did you support or disprove your hypothesis? Were you surprised at the results? Summarize the main things you learned from this section.

3. Evaluate the validity of this statement: The moose are healthier in the presence of wolves because they get more exercise running away from predators. If it is accurate, explain why. If not, how could the sentence be changed to be more accurate?

Section 3: Changes in Weather 

1. In this section, you were introduced to the “Paradox of Enrichment”. In your own words, summarize this phenomenon.

2. How does the current global climate change trends relate to the simulations in this section? Does it correspond with the long or short growing season?

3. Were you surprised at the results of this simulation? Explain your answer.
