Explanation:

Secondary succession starts when an existing ecosystem is disturbed but soil and some remnants remain. Pioneer species are the first to colonize the disturbed area, followed by shrubs, then trees that outcompete smaller plants, until a stable climax community is re-established.

1. First: An intact ecosystem is disrupted by a natural disaster.
2. Pioneer species like grasses and flowers grow.
3. Bushes begin to dominate.
4. Trees become common and outcompete other plants for sunlight.
5. Last: The climax community for the area is established once again.
