Primary succession is a type of ecological succession that occurs in an environment that has been previously uninhabited and where soil has not yet formed, such as after a volcanic eruption, glacial retreat, or the formation of new land from lava.
A disturbance that would trigger primary succession would be:
- **Lava flow**: When lava flows from a volcano and solidifies, it creates a new land surface that is barren and devoid of soil, initiating primary succession.
Other examples include newly exposed rock surfaces after a glacier retreats. In contrast, disturbances like forest fires, floods, or hurricanes typically lead to secondary succession, where soil and some organisms remain present.
