What is the difference between primary succession and secondary succession?
- Primary succession is the first stage of regrowth of an area, and it is followed closely by secondary succession.
- Primary succession occurs on bare rock or sand that has never supported life. Secondary succession occurs on soil that once supported a community.
- Primary succession is the regrowth of a disturbed community. Secondary succession is the forming of a habitat that has never supported a community.
- Primary succession is the process by which the ideal community for a new habitat forms. Secondary succession is the process by which a less desirable community forms.

Today, ecologists realize that
- not all successional pathways are predictable, nor do they all end in a stable climax community.
- succession follows a predictable path and ultimately ends in a stable climax community.
- all succession is, in truth, primary succession.
- every successional pathway ends before it ever reaches a climax community.
