primary succession
series of changes that occur in an area where NO ecosystem previously existed
secondary succession

pioneer species
species that do not need soil to survive; they start the soil building process (lichens and moss)
climax community
a relatively stable state of succession, or the end product of succession
limited factor
a factor that limits the ability of a habitat to sustain a population
microhabitat
a very small specialized habitat, such as the space under a rock
