In what way are primary and secondary succession similar, and how do they differ?
A
Both involve the reestablishment of a community after a disturbance, but secondary succession starts on bare rock.
B
Both involve the establishment of a biological community, but primary succession starts on bare rock while secondary succession occurs in areas with existing soil.
C
Both occur in areas with existing soil, but primary succession involves the reestablishment of a community after a disturbance.
D
Primary succession occurs in aquatic environments, while secondary succession occurs on land.
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.
Identify the two types of succession: primary and secondary succession.
Recognize that primary succession occurs in lifeless areas where there is no soil, such as bare rock surfaces, and involves the gradual establishment of a biological community.
Understand that secondary succession occurs in areas where a community has previously existed but was removed by a disturbance, leaving the soil intact.
Compare the two: both involve the establishment of a biological community, but primary succession starts on bare rock, while secondary succession occurs in areas with existing soil.
