Primary succession takes longer and starts in a new area without soil.
|
|
|
Secondary succession has soil and starts with trees
|
|
|
Secondary succession occurs after a disturbance and is slower that primary succession.

Detailed explanation-1: -Explanation: Primary succession occurs in an environment without previous life, or a barren habitat. Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a wildfire. The newly created volcanic island has no previous life, and is made of rock, devoid of soil.
Detailed explanation-2: -Primary succession is much slower than secondary succession because it begins where there is no soil. It can take several hundred to several thousand years to produce fertile soil naturally. The first pioneer species to colonize the bare rock will probably be bacteria and lichens, which can live without the soil.
Detailed explanation-3: -Primary succession begins with the formation of soil from parent material while secondary succession has soil already present.
Detailed explanation-4: -Secondary succession is faster than the primary succession as the growth media or the soil is already present which allows growth of the plants. The other factors such as the presence of few species also contribute towards the faster rate of growth in the secondary succession.
