  • Environmental resistance limits population growth.

    Population Patterns in Space and Time
  • Populations distribute themselves in different ways.
  • Populations show characteristic patterns of survivorship.

    The Human Population
  • The human population is growing exponentially.
  • The age structure of a population predicts its future growth.
