Vedclass · Answer

(A) Ecological succession is the process by which the structure of a biological community evolves over time.Primary succession occurs in areas where no living organisms have previously existed,such as bare rock or newly cooled lava.Secondary succession occurs in areas where a pre-existing community has been destroyed or removed,such as after a forest fire,flood,or deforestation.These areas still contain soil,organic debris,and biological propagules (seeds,spores,etc.) from the previous community.The assertion is correct because secondary succession indeed occurs in recently denuded areas.The reason is also correct because the process of secondary succession is initiated precisely because an area has been 'bared' (cleared) of its previous vegetation or community due to disturbances like fire or human activity.Therefore,the reason correctly explains why secondary succession occurs in such areas.
