Detailed explanation-1: -After an environmental disturbance such as a volcanic eruption or forest fire, communities are able to replace lost species through the process of succession. Primary succession occurs after a volcanic eruption or earthquake; it involves the breakdown of rocks by lichens to create new, nutrient-rich soils.
Detailed explanation-2: -Example of Primary Succession: Volcanic Eruption Volcanic eruption has destroyed the previous ecosystem. The first organisms to appear are lichens. Then grasses take root in the thin layer of soil. Eventually, tree seedlings and shrubs sprout among the plant community.
Detailed explanation-3: -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-4: -The first stage of succession involves pioneer species. In primary succession, pioneer plants are those that can grow without soil, such as lichens. Lichens begin breaking down a rock.
