Essential Question: Section 9-3: succession What are the possible consequences that can result from a disturbance within a community? Section 9-3: succession Learning Target Predict how a specific change within an ecosystem can impact the organisms within the community.

When an environment is changed over time overview When an environment is changed over time

Primary Succession: happens on “new land”

Pioneer Community: First species to take over an environment (weeds). Primary succession Pioneer Community: First species to take over an environment (weeds).

Primary succession Climax Community: The end of succession. The community is stable for a long time.

Secondary succession Secondary Succession: happens after an environment is destroyed (“old land”)
