Which type of succession occurs after a disturbance when the soil remains intact and regrowth happens from existing soil?

Explanation:
Secondary succession occurs after a disturbance when the soil remains intact. Because the soil and its seed bank, roots, and microbial life survive, plants can regrow from existing material and recolonize quickly, often leading to faster recovery than starting from bare ground. This contrasts with primary succession, which starts on surfaces with no soil at all and requires building soil from scratch. Pioneer species are early colonizers that help initiate the process, but they’re not the type of succession itself; in this scenario the key feature is that soil is still present, enabling rapid regrowth.
