Question

select the correct answer.
what term refers to communities that remain unchanged for long observable periods of time?
a. successive communities
b. stable communities
c. climax communities
d. secondary communities

Explanation:

• Successive communities: Refers to communities that follow one another in a sequence during ecological succession, not communities that remain unchanged.
• Stable communities: While they may have some level of stability, the term "climax communities" is more specific in the context of ecological succession for communities that remain relatively unchanged over long periods.
• Climax communities: In ecology, climax communities are the final stage of ecological succession. They are relatively stable and remain unchanged for long observable periods of time as they are in equilibrium with the environment.
• Secondary communities: Develop after a disturbance in an area that already had an established community (secondary succession), not about long - term unchanged communities.

Answer:

C. climax communities
