DENDROLOGY

Detailed explanation-1: -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. On the Big Island, approximately 32 acres of land are added each year.

Detailed explanation-2: -Primary succession happens when a new patch of land is created or exposed for the first time. This can happen, for example, when lava cools and creates new rocks, or when a glacier retreats and exposes rocks without any soil. During primary succession, organisms must start from scratch.

Detailed explanation-3: -Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a lava flow.

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.
