Why does secondary succession happen more frequently than primary succession? secondary succession occurs in stable communities fewer disturbances and hence fewer changes happen in a community vegetation begins in a barren land where no life exists soil nutrients remain in the area which enables plants to grow

An area going through secondary succession reaches its climax community faster because the area begins with some soil and some plant and animal species. An area that goes through primary succession, on the other hand, begins with no soil and no organisms, so reaching the climax community takes longer.

Secondary Succession is when an ecosystem dies then comes back after x time. While people expanding and growing across the planet, ecosystems are getting smaller and smaller. Grass growing through the cracks of a sidewalk is Secondary Succession. Secondary Succession takes a shorter time than Primary Succession, Primary Succession takes thousands of years while Secondary Succession takes a few hundred years.
