Abstract. Use Excel to create a line graph that shows population growth by plotting the number of bacteria at each time. The activity will reinforce the concepts of exponential growth, logistic growth and carrying capacity. As the population increases and population size gets closer to carrying capacity (N nearly equals K), then \(1- \frac {N} {K}\)is a small fraction that nearly equals zero and when this fraction is multiplied by \(r \times N\), population growth rate is slowed down. Biological Modeling of Populations - Answers to Questions.
