  • Post Lab Questions #1-6
  1. What is a trophic level?
  2. Are most habitats better described as a food chain or a food web? Why?
  3. What role do decomposers and scavengers play in a habitat? What would happen if these organisms were not present?
  4. What would happen if a predator organism was removed from a certain habitat? Use specific examples from your group’s constructed food web.
  5. Can an organism be a secondary and tertiary consumer in the same ecosystem? Explain using examples from the game.
