Study Points

Web Lecture

Read the following weblecture before chat: Studying Populations

Take notes on any questions you have, and be prepared to discuss the lecture in chat.

Study Activity

Perform the study activity below:

Use the Logistic Growth Model at the Virtual Biology Lab to explore how changing the rate r and limiting factor K for two populations can affect their growth and population size.

  • Use the default values and run the model by using the Go button (this is a toggle and turns the model off as well, but let the system run until the population graph stops changing).
  • Lower the rate value for the red population to 0.5 and rerun the model. What happens?
  • Raise the rate value for the red population to 2.0 and rerun the model. What happens?
  • Return the rate to 1.0 but change the K carrying capacity to 250. What happens?
