An example of primary succession is the establishment of plant or animal communities in an area where no soil initially exists, such as bare rocks formed from a lava flow. Secondary succession proceeds more rapidly than primary succession because soil and nutrients often remain and there is usually less distance from the site of the event to soil seed banks and animal life.
