Primary succession will begin after the following:
A) Glaciations (Continental glaciers & Alpine glaciers) - Plants and other life colonize the bare rock.
B) Volcanic Lava Flows - Ex.: Hawaii, Columbia Basalts of ancient Oregon.
C) Volcanic Explosions - Mt. St. Helens, Mt. Mazama (Crater Lake)
D) Faulting raising sea floor -
All of the above examples provide pioneer plants with bare rock or soil to begin succession with.
Conditions that threaten the stability of producer and decomposer populations in an ecosystem jeopardize the availability of energy and the capability of matter to recycle in the rest of the biological community.Producers and Consumers
