Detailed explanation-1: -Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time. For example, primary succession may take place following the eruption of volcanoes, such as those on the Big Island of Hawaii. As lava flows into the ocean, new rock is formed.

Detailed explanation-2: -Primary succession is the process in which plants and animals first colonize a barren habitat. On a newly created volcanic island, for example, after the rock cools, seeds blown by the wind may lodge in crevices. There they can germinate and take root.

Detailed explanation-3: -Primary succession starts at places where no living organisms were present before like a newly formed volcanic island. Before a biotic community of diverse organisms can be established, there must be soil.

Detailed explanation-4: -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-5: -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.
