Which of the Following Describe the Process of Community Succession

Question

Which of the following describe the process of community succession?
A) Dominant species losing out to those that are better colonizers.
B) Later colonizers can often tolerate lower resource levels.
C) Good dispersers typically win in the end.
D) Later colonizers are often more efficient competitors.

Accepted Answer

Community succession involves a series of ecological changes in an area, where the species composition changes over time. Later colonizers can often tolerate lower resource levels (B) because they arrive after initial species have altered the environment, making it less hospitable for fast-growing, resource-demanding pioneer species. Later colonizers are often more efficient competitors (D) because they have evolved to thrive in the conditions created by earlier successional stages, often outcompeting those earlier species for resources and space.
