Primary succession is the series of community changes which occur on an entirely new habitat which has never been colonized before. Examples of such habitats would include newly exposed or deposited surfaces, such as landslips, volcanic lava and debris, elevated sand banks and dunes, quarried rock faces.
Primary Succession occurs on surfaces where no soil exists, And Secondary Succession follows a disturbance that destroys a community without destroying the soil. Primary succession is slow and secondary succession is rapid. Ecological succession refers to orderly changes in an ecological community.econdary succession occurs on previously occupied land such as an area that has been devastated by a forest fire. Soil with organic content is found on this piece of land and organisms may be present at the beginning.
