What is the difference between primary and secondary succession? In primary succession the environmental conditions become optimal; in secondary succession habitats are opened up for less competitive species. Primary succession involves competitively dominant species while secondary succession infrequently exclude less competitive species after a moderate disturbance. Primary succession happens before secondary succession. In primary succession, newly exposed or newly formed land is colonized by living things; in secondary succession, part of an ecosystem is disturbed and remnants of the previous community remain.
