Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Secondary succession<span> is a much </span>more rapid<span>process than primary </span>succession<span> because the soil and nutrients are already available. Hope this helps.</span>
<span>Secondary succession in healthy ecosystems following natural disturbances often reproduces the original climax community. Ecosystems may or may not recover from extensive human-caused disturbances.</span>
Changes in the environment may leave individuals less well adapted to compete successfully for resources such as food, water and mates. Sometimes an entire species may become unable to compete successfully and reproduce. These problems can lead to extinction.
