Verified step by step guidance1
Understand the concept of ecological succession, which is the process by which the structure of a biological community evolves over time.
Differentiate between primary and secondary succession. Primary succession occurs in lifeless areas where there is no soil, while secondary succession occurs in areas where a community has been disturbed but soil remains.
Recognize that primary succession begins in environments such as bare rock, sand dunes, or lava flows, where soil has not yet formed.
Identify the initial colonizers in primary succession, often lichens and mosses, which can grow on bare surfaces and contribute to soil formation through their biological activities.
Conclude that primary succession occurs without soil, as it involves the gradual development of soil through the breakdown of rock and accumulation of organic material from pioneer species.
