Ecological succession refers to

- B. The competition among species for limited resources
- C. The process of natural selection in a population
- D. The gradual and predictable change in a community over time
Correct Answer: D. The gradual and predictable change in a community over time
Explanation
Ecological succession can be primary or secondary. Primary succession occurs in areas where no previous community existed, such as on bare rock or after a volcanic eruption. Secondary succession occurs in areas where a previous community has been disturbed, such as after a forest fire or human disturbance. Throughout the succession process, the community gradually changes in terms of species composition, population sizes, and community interactions, leading to a more stable and mature ecosystem.
