Ecology Pre-LabName: _____________________________________ Section: ______Go to the website virtualbiologylab.org and click on Ecology > Population Ecology. Scroll down to Model 1 – LogisticGrowth and click on Directions to read about the model. Then, click on Launch Model and complete Exercise 1 using theinstructions below. Turn in your completed worksheet in the first 10 minutes of your enrolled lab.After completing this pre-lab, you should be able to…•Describe how initial population size, growth rate, and carrying capacity affect patterns of population growth.Exercise 1: Logistic GrowthUse the Logistic Growth simulation to examine how initial size, per capita growth rate, and carrying capacity affectpopulation growth. Set carrying capacity (K) at 1000 for both populations. Use the following parameters for initialpopulation size (N) and per capita growth rate (r). After adjusting parameters, always click ‘Set up’ before running eachtrial.Click ‘Go’ to start each trial. Click ‘Go’ to stop the trial when both population have reached K (Hint: look at the firstgraph). You can use the slider at the top of the window to adjust speed of the simulation if needed. Record your resultsin the table below.Red (N)Blue (N)Red (r)Blue (r)Red Pop. Time to K (t)Blue Pop. Time to K (t)10101.0 *1.0 *20102.02.0
