Which one of the following statements is correct for secondary succession?

Succession is a process that starts in an area where no living organisms are there; these could be areas where no living organisms ever existed, such as a bare rock, or in areas that somehow, lost all the living organisms that existed there. The former is called primary succession, while the latter is termed secondary succession. 

Examples of areas where primary succession occurs are newly cooled lava, bare rock, and newly created pond or reservoir. The establishment of a new biotic community is generally slow. Before a biotic community of diverse organisms can become established, there must be soil. Depending mostly on the climate, it takes natural processes several hundred to several thousand years to produce fertile soil on bare rock.

Secondary succession begins in areas where natural biotic communities have been destroyed, such as in abandoned farm lands, burned or cut forests, and lands that have been flooded. Since some soil or sediment is present, succession is faster than primary succession.
