  15. What is primary succession?
    When a place that had no organisms before it was disturbed but organisms like moss and lichens come in and then they die out to make way for better soil for better, more complex organisms.
  16. What is primary succession?
    When a place had organisms, it got diturbed, but then moss and lichens come back, die out and make the soil more fertile for more complex organisms et cetera.
  17. What are the moss and lichens called that started primary and secondary succession?
    The pioneer species.

    An energy pyramid.

    (A food pyramid is WRONG)
