Questions and Answers

What is the primary purpose of an energy pyramid?

  • Show the physical location of different species in an ecosystem
  • Display the number of organisms in each trophic level
  • Illustrate the reproductive capabilities of each trophic level
  • Demonstrate and quantify the flow of energy in an ecosystem (correct)

    • Which trophic level in an ecosystem contains organisms that make their own food?

  • Tertiary consumers
  • Secondary consumers
  • Primary consumers
  • Producers (correct)

    • In an energy pyramid, where are organisms with higher energy levels typically located?
