Student Objectives

Students will be able to describe population dynamics, including the following:
  • models that describe the growth of populations (e.g. r- and k-selection).
  • regulation of population size by abiotic factors (e.g. niche availability, pollution),
  • regulation of population size by biotic factors (e.g. food availability, predation),
Students will be able to describe community dynamics, including the following:
  • Predator-prey interactions,
  • parasitism
  • commensalism
  • symbiosis
  • affects of abiotic factors that affect community size (e.g. habitat size)

Students will be able to describe ecosystem dynamics, including the following:

  • energy flow through an ecosystem (e.g. food web and trophic levels),
  • carbon cycle,
  • nitrogen cycle,
  • oxygen cycle,
  • phosphorus cycle,
  • sulfur cycle

Students will be able to discuss global issues, such as the following:

  • local population extinction due to habitat destruction, pollution, non-native species, etc.,
  • affect of human activities upon local ecosystems and biomes.
