What is the difference between primary and secondary succession?

1 Answer

Primary succession is on pristine habitats, while secondary on disturbances.

Explanation:

  1. The primary succession occurs following an opening of a pristine habitat, e.g., on lava flow, an area left from retreated glacier, or abandoned mine.
  2. The secondary succession is a response to a disturbance e.g., forest fire, tsunami, flood, etc.
