Explanation:

Solution. Exp: Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction. Statement 1 not correct: In primary succession on a terrestrial site the new site is first colonized by a few hardy pioneer species that are often microbes, lichens and mosses. Secondary succession occurs when plants recognize an area in which the climax community has been disturbed. Secondary succession is faster than primary succession. Statement 2 is correct: A seral community is an intermediate stage found in an ecosystem advancing towards its climax community. In many cases more than one seral stage evolves until climax conditions are attained.
