Secondary succession differs from primary succession in several key ways:
1. Secondary succession occurs on previously disturbed or damaged ecosystems, such as those affected by fires, floods, or human activities, while primary succession begins on completely barren surfaces such as bare rock or land with no previous vegetation.
2. In secondary succession, some soil nutrients may already be present, as opposed to primary succession where pioneer species like lichens and mosses must first colonize and break down rock to form soil.
3. Secondary succession typically starts with the reestablishment of vegetation and soil organisms in an ecosystem that already had plant life, whereas primary succession begins in environments where no plants have previously grown.
Overall, secondary succession occurs in areas where an ecosystem has been disrupted and is in the process of recovering, while primary succession starts in completely pristine or barren environments.
