Explanation: 

Detailed explanation-1: -Q. So, how does an ecosystem start if there is no soil? Moss and lichen break down rock and lava and produce soil. Moss and lichen are air borne and they move by the wind to start in a secondary succession environment.

Detailed explanation-2: -What is Ecological Succession? Ecological succession is the steady and gradual change in a species of a given area with respect to the changing environment. It is a predictable change and is an inevitable process of nature as all the biotic components have to keep up with the changes in our environment.

Detailed explanation-3: -that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil.

Detailed explanation-4: -The order of secondary succession is pioneer species, intermediate species, and finally climax community. The pioneer species are the first to colonize and include the producers like lichens and mosses. The intermediate species appear next and include shrubby plants and small trees.
