occurs in areas where a community that previously existed has been removed by a disturbance (farming, fire, flood, etc); begins with soil; takes less time than other succession

• primary succession

• secondary succession

series of events through which a stable ecosystem forms in a previously lifeless areas; begins with no soil as rock broken down and soil forms plant take root; this continues until area reaches climax community if not disturbed; takes a long time

• primary succession

• secondary succession

first organisms to appear in areas of primary succession are often mosses or lichens

final stage of succession, populations of plants or animals remain stable and exist in balance with each other and their environment until nature or humans cause a disturbance
