What Is The Difference Between Primary Succession And Secondary Succession

Secondary succession succession that follows the disruption of a pre existing community that existed in the same ecosystem is called secondary succession.

What is primary succession. Key differences between primary succession and secondary succession. In biology when different natural communities come into existence and then get replaced it is called ecological succession. Primary succession succession that begins in new habitats or lifeless areas that are uninfluenced by pre existing communities is called primary succession.

The pioneer species of secondary succession are the species already present within the previous ecosystem. Primary and secondary are two types of ecological succession. The pioneer species of primary succession enter the ecosystem from the outside environment. When natural communities are developed in barren habitat with no soil or extremely less soil it is called primary succession.

The pioneer species in primary succession are mostly lichens followed by algae and fungi. Secondary succession differs from primary succession in that it begins after a major disturbance such as a devastating flood wildfire landslide lava flow or human activity farming road or building construction or the like wipes away part of a landscape. The main difference between primary and secondary succession is that primary succession occurs in the land where there is no initial vegetation whereas secondary succession occurs in a land that has primary vegetation. Primary succession occurs in the lifeless or barren area while secondary succession occurs in an area which has been recently got deprive of life and was previously inhabited.
