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.
Recognize that during ecological succession, species diversity typically increases as new species colonize the area and establish themselves.
Consider that as succession progresses, the community becomes more stable and resilient to disturbances, contrary to becoming less stable.
Note that the number of trophic levels generally increases as the ecosystem becomes more complex, rather than decreasing.
Identify that pioneer species dominate the early stages of succession, but over time, they are replaced by more competitive species as the community matures.
