Detailed explanation-1: -An example of primary succession is the establishment of plant or animal communities in an area where no soil initially exists, such as bare rocks formed from a lava flow. Other examples are the colonization of a barren area following a severe landslide or recently exposed land from retreating glaciers.

Detailed explanation-2: -In primary succession, there is no soil and it needs to form. This process takes time, as pioneer species must colonize the area, they must die, and as this happens over and over again, soil forms. Secondary succession happens after some sort of disturbance.

Detailed explanation-3: -Primary succession is the succession that occurs in areas that have no living things such as areas without soil or areas where the soil cannot really sustain living things. Primary succession occurs when this area first becomes colonized with living plants or organisms.
