Primary and secondary succession

Similarities

Succession is a community is created and changes over time
Both lead to a climax community- a stable community
Both communities start with pioneer species- the first species that are adapted to withstand extreme conditions

Differences

Primary succession develops a new community from scratch
Secondary succession happens on a previously existing community that has been cleared.
Pioneer species for secondary succession are adapted differently- they grow quickly, can disperse quickly and have a short life span

Overall comparison

Primary succession creates a new community such as by the seaside, where secondary succession develops a new community that has been cleared. These existing communities can be cleared by deforestation, burning or other human activity.
