Animations
21.1: Activity: Unrestrained population growth
Use this interactive simulation to explore the concept of exponential growth discussed in section 21.3 of your textbook.
21.2: Activity: Restrained population growth
Use this interactive simulation to test what happens as a population approaches and exceeds its carrying capacity.
21.3: Activity: Predator-prey interactions
Use this interactive simulation to explore how the prey and predator population size changes with different growth rates and different levels of predation.
21.4: Activity: Population cycles
Explore a common interaction between organisms of differing species, the predator to prey interaction.
21.5: Activity: Human population growth
Learn more about the rapid explosion of the human population in the last few hundred years. Interactive controls at the end of the activity allow you to test the effects of various birth and death rates.
