Unit 4: Population and Human Ecology

Essential Questions: How do we study populations? How is the human population changing and affecting the world?

Standards:

  • SEV3. Students will describe stability and change in ecosystems.

d. Explain how biotic and abiotic factors affect populations.

  • SEV5. Students will recognize that human beings are part of the global ecosystem and will evaluate the effects of human activities and technology on ecosystems.
  • Describe factors affecting population growth of all organisms, including humans. Relate these to factors affecting growth rates and carrying capacity of the environment.
  • Describe the effects of population growth, demographic transitions, cultural differences, emergent diseases, etc. on society stability.
  • Explain how human activities affect global and local sustainability.
  1. Describe how political, legal, social, and economic decisions may affect global and local ecosystems.

Objectives: Students will be able to…

  • Define population and the three traits used to describe populations: size, density, and dispersion
  • Explain how populations change in size and apply the formula for growth rate
  • Differentiate between the two types of population growth
  • Describe and give examples of density-dependent and density-independent factors that limit population growth
  • Define reproductive potential and list traits of organisms that have high and low reproductive potential
  • Contrast r-selected and K-selected species and give examples for each
  • Compare and contrast developed versus developing countries and give examples for each
  • Explain factors that affect a country’s population growth
  • Apply the use of age structure diagrams to predict changes in population size
  • Define doubling time and apply the Rule of 70 formula to actual populations
  • Describe the Demographic Transition Model
  • List and explain problems with human population growth
  • Identify and debate possible solutions for slowing human population growth
