Verified step by step guidance

1. Understand the concept of ecological succession: It is the process by which the structure of a biological community evolves over time. It involves changes in species composition and community structure following a disturbance or the creation of new substrate.
2. Identify the key characteristics of ecological succession: It typically involves a series of stages, starting with pioneer species colonizing an area, followed by intermediate species, and eventually leading to a stable climax community.
3. Analyze the given options to determine which one fits the definition of ecological succession: A river eroding its banks is a geological process, not a biological community change. A plant using photosynthesis is a biological process, but not related to community change. A predator hunting its prey is an interaction within a community, but not a succession process.
4. Focus on the option 'A forest regrowing after a wildfire': This describes a secondary succession, where an existing community has been disturbed (by wildfire) and regrows over time, eventually restoring the ecosystem.
5. Conclude that 'A forest regrowing after a wildfire' is the correct example of ecological succession, as it involves the gradual recovery and development of a biological community following a disturbance.
