DENDROLOGY

Detailed explanation-1: -The rocky material left behind by a retreating glacier forms what is called a moraine. When primary succession occurs on a moraine, which life-forms will help create the soil by breaking down bare rock? As ecosystems move through the stages of succession, the populations of organisms in them change.

Detailed explanation-2: -Some of the first organisms to appear during primary succession, the pioneer species, include lichen, algae, fungi, and mosses. These organisms can help break down rock and form soil.

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: -Primary succession refers to the establishment of a community in an uninhabited area such as rocks. Process of primary succession: Primary succession is seen in areas where volcanic eruptions occur. When the lava has cooled and hardened, it forms rocks or barren land.
