  • What is the ultimate source of energy for all ecosystems?
    The Sun
  • Define biodiversity
    the amount of different living things in an area
  • What belongs in the missing trophic level?
    Primary Consumer
  • Why is the forest food web more sustainable?
    It has more biodiversity so if something were to happen to one of the populations, there would still be other sources of energy to keep things stable
  • Which organism recieves the least amount of energy and how much is it?
    Human-80 J
  • Where is the most energy and biomass found at?
    Producers
  • Which is NOT an autotroph (producer)? Algae, wildflower, mushroom, douglas fir tree
    mushroom
  • What is an autotroph and heterotroph?
    autotroph-producer heterotroph-consumer
  • What is something that both primary and secondary consumers have in common?
    They both get energy from other living things
  • This child's work is incorrect. Explain what you would do to make it correct-be detailed
    it's missing arrows. Must explain which way arrows would be pointing to get credit
  • If a species is completely removed from an ecosystem, what decreases in that area?
    plants
    biodiversity and sustainability
    only biodiversity
    primary consumers
  • Which list only abiotic factors
    rain, temperature, soil

    Tuna
  • Which ecosystem has the most sustainability?
    Ecosystem 4
  • Which letters represent Apex Predators?
    I and E
  • If the producers create 5,000 J of energy, how much is available for the secondary consumers?
    50 J
  • Which shows the interaction between a biotic and abiotic factor?
    Bear and Cave
  • Which letters represents the producers?
    A and B
  • Which food web is more sustainable and why?
    Forest Food Web because it has more biodiversity
  • If the mice have 840 J of energy, how much energy do the hawks receive?
    8.4 J
  • What do the arrows in a food chain and web show us?
    Which way the energy flows
  • What percentage of energy is passed from one trophic level to the next?
    10%
  • Name one organisms that depends directly on primary consumers for its energy source?
    Monkeys, Lions, or mongoose
