Verified step by step guidance1
Begin by understanding the concept of ecological succession, which is the process by which the structure of a biological community evolves over time.
Identify the types of ecological succession: primary succession and secondary succession. Primary succession occurs in lifeless areas, while secondary succession occurs in areas where a community has been disturbed but life still exists.
Consider the characteristics of primary succession. It starts in areas where no life has previously existed, such as bare rock or sand dunes, and involves the gradual establishment of a biological community.
Recognize that primary succession involves pioneer species, which are the first organisms to colonize barren environments. These species help create soil and conditions suitable for other species to follow.
Conclude that primary succession is the type of ecological succession that occurs in an area where no life has previously existed, as it involves the initial establishment of a community in a previously uninhabited environment.
