    are the stages primary and secondary succession basically the same except for the fact that primary happens on bare land, so is much slower, and secondary starts on soil, making it faster???

    From my understanding in A-level biology:

    Primary succession is the succession of ecological life in very harsh environments where life hasn't existed before e.g. lava flow or under a retreated glacier and this is where you will see the pioneer species which start to normalise the habitat.

    Secondary succession is when an event (e.g. hurricane, forest fire) wipes out or reduces a previously established ecosystem and then starts growing again.

    So you are right that the main differences are that secondary succession starts on pre-existing soil so therefore is much quicker than primary.
