DENDROLOGY

Detailed explanation-1: -Primary Succession After a Volcano Lava flows down the side of the volcano, destroying everything in its path, but when it cools, it forms new land. Initially, the new land will be barren with nothing living in the area. But after some time, simple organisms will begin to colonize the new land.

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. As lava flows into the ocean, new rock is formed.

Detailed explanation-3: -Primary succession occurs in an environment without previous life, or a barren habitat. Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a lava flow.
