8. Bare rock is exposed due to some type of disturbance like a retreating glacier or volcanic eruption. No soil is present.
Pioneer species, like lichens and mosses, establish themselves on the rock substrate.
Pioneer species die and decay, providing soil and nutrients for other plant species like shrubs and small trees.
Small and Large trees begin to grow, and the community reaches an equilibrium or balance. This results in a climax community.
Primary Succession: The establishment of new community where none existed before.

Species:
Lichens

11. Climax Community
Stable, end stage of ecological succession in which organisms use resources efficiently and balance is maintained.

12. Organisms are driven away or killed by some type of disturbance, like a forest fire, leaving behind only the soil.
Pioneer species, like grasses and weeds, begin to grow from the soil. Roots and seeds left over may also begin to grow again.
Some pioneers species die and are replace or outcompeted by other species like shrubs and small trees.
Small and Large trees begin to grow, and the community reaches an equilibrium or balance. This results in a climax community.
Secondary Succession: The reestablishment of community following disturbance.

13. Habitat Vocabulary pg 109
Primary Succession- when an area regrows after a disturbance has removed all plants and SOIL Secondary Succession- when an area re-grows itself after a disturbance has removed all plants and the soil still remains Pioneer Species- the first species to start growing in an area Climax Community- when an area has grown into a stable community

14. Climax Community
Stable, end stage of ecological succession in which organisms use resources efficiently and balance is maintained.
