What Is The Difference Between Primary Succession And Secondary Succession

When natural communities are developed in barren habitat with no soil or extremely less soil it is called primary succession.

The pioneer species of primary succession enter the ecosystem from the outside environment. Key differences between primary succession and secondary succession. Primary and secondary are two types of ecological succession. In biology when different natural communities come into existence and then get replaced it is called ecological succession.

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. Secondary succession succession that follows the disruption of a pre existing community that existed in the same ecosystem is called secondary succession. Primary succession occurs in the lifeless area or barren area whereas secondary succession occurs in the area which has been deprived of life recently or was inhabited previously. What is primary succession.

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. 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 pioneer species in primary succession are mostly lichens followed by algae and fungi. Time taken for the completion of the process in primary succession is more than 1000 years while secondary succession takes place around 200 for its completion.
