In the context of ecological succession, lichens and mosses are considered pioneer species. What type of succession do they typically initiate?
A
Climax succession
B
Tertiary succession
C
Primary succession
D
Secondary succession
Verified step by step guidance1
Understand the concept of ecological succession, which is the process of change in the species structure of an ecological community over time.
Identify the role of pioneer species, which are the first organisms to colonize a barren or disturbed environment.
Recognize that lichens and mosses are typical pioneer species due to their ability to survive in harsh conditions and contribute to soil formation.
Differentiate between types of succession: primary succession occurs in lifeless areas where soil has not yet formed, while secondary succession occurs in areas where a community has been disturbed but soil remains.
Conclude that lichens and mosses typically initiate primary succession, as they colonize bare rock or other surfaces where no soil exists, leading to the gradual development of a more complex ecosystem.
