Explanation:
Primary Succession is an ordered series of events that occurs in a previously uninhabited region where a stable ecosystem now forms,
it starts with pioneer species, lichen, mosses and fungi – that can grow on rocks and exposed land. As they die and decompose, their organic matter becomes the foundation for a thin layer of soil.
Once grasses and weeds begin to grow, soil formation is accelerated and more animal species begin to appear. The environment retains moisture, and ideal conditions are created for the growth of shrubs and small trees. This is followed by larger trees and animals,
Examples of Primary Succession
Volcanic eruptions
Retreat of glaciers
Flooding accompanied by severe soil erosion
Landslides
Nuclear explosions
Oil spills
Abandonment of a man made structure, such as a paved parking lot
Secondary succession secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation (such as after tree-felling in a woodland) and destructive events such as fires.
