Detailed explanation-1: -A volcano in a mountainous, wooded region erupts, spewing tons of ash and destroying the forested area around the volcano. If the volcano remains dormant during the next 1000 years, what will probably happen? a. The area will be repopulated by trees, eventually becoming a forest again.
Detailed explanation-2: -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.
Detailed explanation-3: -When disturbances destroy an existing habitat, secondary succession may occur. This disturbance could be a forest fire or volcanic eruption. The plants and animals are gone, but the soil remains. Secondary succession begins on existing soil.
Detailed explanation-4: -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.
Detailed explanation-5: -Answer and Explanation: The correct answer is c. lichens. Lichens are most likely to be pioneer species in a newly formed volcanic island.
