Both primary and secondary succession involves ecosystems recovering from a disruptive event. Thus, option "B" is correct.
<h3>What is Primary succession?</h3>
Primary succession occurs following an opening of pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.
