Explanation:
Detailed explanation-1: -primary succession. Primary succession occurs when new land is formed or bare rock is exposed to provide lifeless habitat for the organisms for the first time. When the volcano erupts, it forms a small island (composed of rocks) that provides lifeless habitat for the organism (for the first time).
Detailed explanation-2: -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.
