How do ecosystems change over time?
OBJECTIVES:
-Identify Abiotic and Biotic Factors in an ecosystem
-Discuss their importance
-Observe how the succession plot has changed over time

3. Succession Plot
Go outside and examine succession plot from the week before
Make observations along with predictions for another week
Note any new growth on the plot along with comparisons to the undisturbed ground around it

4. Outside Expecatations
-Voice Level 0 in the hallway
-Voice Level of 1 or 2 outside while you examine the succession plot
-Classes are very near the plot, so be mindful of your volume!
Stay in one spot in close vicinity to the plot where you can see and draw
Do not wander!

22. 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.

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

26. 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.

27. 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

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