2. Which of the following is an example of a pioneer species in primary succession?

a

Oak trees

b

Grasses

c

Lichens and mosses

d

Shrubs

3. Secondary succession typically occurs in an area where:

New volcanic rock has formed.

b

An ecosystem was completely destroyed, leaving no soil.

c

A forest fire has cleared existing vegetation, but soil remains.

d

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.

T

True

F

False

9. Describe three major differences between primary and secondary succession.
