About seven years ago, a group of 13 female and 4 male snowshoe hares were introduced to Granite Island, which is 120 km from the nearest land mass. There were no indigenous hares or any predators on the island. A scientist visited the island every four months to gather population data. The data is shown below in graphical form.

a) What type of population growth pattern does the graph reveal, during the A time from 10 to 30 months? b) The S-shaped pattern of growth of the snowshoe hares has three phases. Draw two vertical lines on the graph provided on the previous page to indicate where the phases are changing, and then label each phase. c) Write out the mathematical equation of the model that explains the middle phase, where the most dramatic increase in population occurs. d) At about 60 months, the hare population stabilizes. Explain why this happens. I
