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: -Succession that begins in an area with no remnants of an older community is called primary succession. For example, in Mount Saint Helens, Washington, an erupting volcano decimated all nearby living organisms. Changes in this community will continue for centuries.
