Questions and Answers

What is the primary measure of species diversity in a community?

  • The resistance of the community to invasion by exotic species
  • The total biomass produced by the community
  • The complexity of the trophic structure
  • The number of species and their relative abundance (correct)

    • How do more diverse communities typically differ from less diverse communities?

  • They typically have more dominant and keystone species
  • They produce less biomass and show more year-to-year variation in growth (correct)
  • They are less resistant to invasion by exotic species
  • They have simpler trophic structures with fewer food chains

    • What is the key factor that determines the length of a food chain according to the energetic hypothesis?

  • The presence of keystone species
  • The abundance of primary producers
  • The efficiency of energy transfer along the chain (correct)
  • The complexity of trophic interactions
