Oak trees
Grasses
Lichens and mosses

3. Secondary succession typically occurs in an area where:
New volcanic rock has formed.
An ecosystem was completely destroyed, leaving no soil.
A forest fire has cleared existing vegetation, but soil remains.
A new island emerges from the ocean.
4. The final, stable community in an ecological succession is known as the community.
5. succession begins in an area where no life was present, such as bare rock.
6. The process by which one community replaces another over time is called ecological .
7. Primary succession occurs faster than secondary succession because soil is already present.
True
False
8. A climax community is always composed of the same species regardless of the geographic location.
True
False
9. Describe three major differences between primary and secondary succession.
10. Explain the role of pioneer species in the process of primary succession.
