Question

Compare AND contrast primary and secondary succession.

Answer 1

The basic difference between primary and secondary succession is the presence of soil. When primary succession begins, soil is not present; in the case of secondary succession, soil is already in place.

Answer 2

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.In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
