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.

Detailed explanation-2: -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.

Detailed explanation-3: -Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time.
