Secondary succession differs from primary succession in that it begins in an area where plants used to grow but have been removed due to a disturbance, such as a fire or flood. In secondary succession, soil nutrients are already present and the process starts with the regrowth of plants from seeds or roots that remain in the soil. In contrast, primary succession starts on bare rock or land where no plants have previously grown, and the first organisms to colonize the area are typically lichens and mosses that break down the rock and create soil over time.
