Definition: Ecological Succession • Gradual, sequential replacement of populations in an area • Existing communities are replaced
The Process Of Ecological Succession Pioneer Species Seral CommunityClimax Community
Pioneer Species • First to colonize • Examples: Grasses, mosses, and lichens
Seral Community • Second step in ecological succession • Intermediate communities are replaced repeatedly
Climax Community • A stable collection of plants and animals • A balanced system if it is undisturbed
Types of Ecological Succession Primary Succession Secondary Succession
Primary Succession • Occurs in an area that was not previously occupied. • It takes 1000 years for primary succession to get to a climax community • Example: sand dune and rocks
Secondary Succession • Occurs in an area that is cleared and abandoned • Examples: soil left after a fire, a volcanic eruption, or human activity.
