Which is a difference between plant populations in primary succession and secondary succession?

Primary succession occurs following an opening of a 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.

Pioneer species in primary succession grow in environments without soil, while pioneer species in secondary succession grow in environments that already have soil.

Explanation:

The two types of ecological succession are primary and secondary. Primary succession occurs in locations that do not currently have life or soil. Secondary succession occurs in an environment that has life and soil but has had a significant change occur. A wildfire is an example of change that could lead to secondary succession. The first plants to grow during either type of succession are called pioneer species.

Therefore, pioneer species in primary succession grow in environments without soil, while pioneer species in secondary succession grown in environments that already have soil.
