Detailed explanation-1: -Primary succession happens when a new patch of land is created or exposed for the first time. This can happen, for example, when lava cools and creates new rocks, or when a glacier retreats and exposes rocks without any soil. During primary succession, organisms must start from scratch.
Detailed explanation-2: -Primary succession follows the formation of a totally new habitat, such as when a lava flow or a receding glacier creates or reveals new land which is devoid of soil or vegetation.
Detailed explanation-3: -Primary succession occurs in an area that has not been previously occupied by a community. Places where primary succession occurs include newly exposed rock areas, sand dunes, and lava flows. Simple species that can tolerate the often-harsh environment become established first.
