Answers to study questions Lecture 10, Competition 1. Draw a plot of population growth versus time in which you contrast two population growth cures: (a) one in which the population grows following Δ N / t = rN. (b) one in which the population grows following N / t = rN (1- N/K ). Assume that the populations start at a very small size (near zero), that r > 0, and that the carrying capacity, K , is 50. Answer: Your graph should look something like this. The blue curve shows “exponential growth” and the red curve shows population growth under the Logistic Equation. Note that you do NOT have an equation in your text or lecture notes that will allow you to generate these graphs by “plug and chug” (you need calculus to generate those equations). So, you need to produce these answers by looking at the Logistic Equation and thinking about how a rate of change in population size translates into the time course of population size. 2.
