DENDROLOGY

Detailed explanation-1: -Weeds will grow, followed by grass, small plants and shrubs, then trees will follow in years to come. Animal life will be supported as this growth of vegetation occurs.

Detailed explanation-2: -Explanation: Primary succession commonly occurs after a volcanic eruption or a glacier recedes, because these areas have been stripped of organic matter. Primary succession is the process by which pioneer species colonize an area otherwise uninhabitable for plant life and generate nitrogen for other plant communities.

Detailed explanation-3: -Primary succession occurs after a volcanic eruption or earthquake; it involves the breakdown of rocks by lichens to create new, nutrient-rich soils. The first species to colonize an area after a major disturbance are called pioneer species; they help to form the new environment.
