Explanation:

Statement 1 is not correct: The species that invade a bare area are called pioneer species. In primary succession on rocks, these are usually lichens which are able to secrete acids to dissolve rock, helping in weathering and soil formation. Statement 2 is correct: Seral species are found between the Primary and Climax communities. Statement 3 is not correct: Secondary succession is faster than primary succession, Ecological succession is the process by which communities of plant and animal species in an area are replaced or changed over time. The pioneer community is the first plant to colonize an area. The climax community is the final stage of succession. A climax community is more stable, mature, complex, and longlived. The successional stage or series refers to the stage preceding the climax community. A stage in succession or a seral community is a transitional community that forms and is replaced during succession. In contrast to primary succession, secondary succession begins on a well-developed soil that has already formed at the site. As a result, secondary succession occurs at a faster rate.
