Primary Succession have the right to be defined as the procedure of development in an area the was formerly uninhabited, barren, unoccupied and there was no early stage vegetation. On the various other hand, Secondary Succession have the right to be identified as the development of the community in together area i m sorry was previously occupied, inhabited and also that has actually primary vegetation yet got disturbed or damaged because of some exterior or internal factors.

You are watching: Explain the difference between primary and secondary succession

The example the Primary succession is the newly formed bare rock, desert, ponds, etc., when the area covered under deforestation, or influenced by natural disasters such as flood, earthquake, etc. Room the instances of secondary Succession.

The eco-friendly succession deserve to be defined as the gradual and also natural process, that the advancement of the biological community. The moment taken for such breakthrough can be decades or end million of years. The process begins with the development of a pioneering community, initiate indigenous the ceiling rock, the lichens, and couple of plants species.

The following is the advancement of the intermediate species which has the grasses, shrubs, trees like pines, etc. The critical is the orgasm community which got developed into the oak and also hickory varieties of shade-tolerant trees.

Succession‘ is a part of directional temporal transforms in a neighborhood – which describe the changes a solitary location; these have the right to be seasonal, diurnal or lengthy term changes. The procedure of ecological succession is separated into two components – Primary sequence and second Succession. In this article, we will mark out the difference in between the both along with the tiny description ~ above them.

Basis for ComparisonPrimary Succession secondary Succession
MeaningIt is the kind of ecological succession, which occurs or begin from the barren, uninhabited and unoccupied areas, such as the newly created pond, rock, dunes, etc. Such kind of succession, which wake up in the area where there to be the presence of life previously but got abandoned as result of natural disturbances, such together flood, tsunami, earthquake, etc.
Where that occursIt occurs in a lifeless or barren area.It wake up in one area, which has been recently acquired deprive that life and also was formerly inhabited.
Time taken because that the perfect of the process1000 years or more.50-200 years.
SoilThere is the absence of soil at the beginning of the process, and also the condition is not suitable for maintain life. The floor is present, in addition to some organisms.
HumusThe absence of humus, together there is no soil.Secondary succession shows its presence in the existence of humus.
Seral CommunityThere are many intermediary seral community.There are couple of intermediary seral ar as contrasted to main succession.
Pioneer CommunityIt is present and comes indigenous outside.It gets creates from the migrants and also previous occupants.
Favorable environmentIn the beginning, the atmosphere is unfavorable. The environment is favorable, since the beginning.
Reproductive structureAbsent of any type of previous community.Present the the previous ar use come live in the area.

Definition of main Succession

Primary succession is the initial phase of the breakthrough of any type of community. Together it starts cultivation from the area where there is no suitable condition because that sustaining life. Slowly the breakthrough goes on, native the barren area, rocks and also non-vegetative areas to the development of the occurred community. The evolution is so slow-moving that it takes hundreds of years to construct such area.


Primary succession is the an initial life form to show up in any kind of environment, whether it is a terrestrial, marine or fresh water. In this case, over there is no previous living material present. And also the biology which create themselves in the initial phase are referred to as the main colonizers or pioneer and community of that types is referred to as primary community. Lichens and also algae room the typical examples that this succession.

Definition of second Succession

The community that existed previously, however has to be removed as result of the natural disturbances. Also the land quiet marks the visibility of the important nutrition, i m sorry is forced by all develops of life come grow. This type of sequence occurs in the forest, which has been reduced recently, plowing fields, submarine lands and also the area i beg your pardon were damaged due to natural calamities.


Thus it have the right to be said that second Succession occurs once the floor of primary succession get disturbed, due to some biological cause orinternal factors.

Key Differences in between Primary sequence and secondary Succession

Given listed below are the substantial points, because that distinguishing in between both sort of ecological succession:

Primary Succession is identified as the kind of environmental succession, which wake up or begin from the barren, uninhabited and also unoccupied areas, such together the newly developed pond, rock, dunes, etc., when such sort of succession, which wake up in the area wherein there to be the presence of life previously however got abandoned because of natural disturbances favor deforestation, natural calamities (flood, earthquake, tsunami), the field with no vegetation is recognized as Secondary Succession.Primary Succession occurs in the lifeless or barren area while an additional Succession occurs in an area, which has actually been newly got deprive the life and also was previously inhabited.Time taken for the completion of the procedure in Primary succession is much more than 1000 years while second Succession bring away place around 200 because that its completion.There is the absence of soil and humus in ~ the beginning of the process, and the problem is not perfect for maintain life, however in second Succession soil and humus are present, together with some organisms.Intermediary seral and pioneer community are present in number in Primary sequence whereas the visibility of intermediary seral community few in numbers and pioneer neighborhood gets develops from the migrants and also the previous occupants.In the beginning, the setting is unfavorable because that the growth in Primary succession but in instance of secondary Succession, the environment is favorable, since the beginning of development.

We can say that the ecological sequence is the sequential progression, evolving the brand-new species. These transforms at the stage of climax condition produce a steady community, which is overcame by a certain kind of varieties as those were just able to cop increase in that environment. Thus this sort of succession is necessary and fruitful to the environment, to maintain the eco-friendly balance.
