Introductory Activity: Greater Yellowstone Ecosystem Biotic Characterization
 
  1. While watching the documentary film “Yellowstone: America’s Sacred Wilderness”,
    identify and list all trophic (feeding) interactions between organisms (e.g. wolf
    preying on elk calf, grizzly foraging for berries; osprey catching fish, etc)

  2. Categories these organisms and interactions into the main structural levels
    for the ecosystem:
    1. Autotrophs
    2. Heterotrophs
      1. Consumers
      2. Primary Consumer
      3. Secondary Consumer
      4. Decomposers
      5. Inorganic and Dead Organic Matter
  3. Using information from the film and additional web searches or other resources,
    construct a food web diagram of the Yellowstone Ecosystem.
  4. Explore the YNP official web site: http://www.nps.gov/yell/
