Final answer:
The correct answer is b. Communities, community ecology, evolution.
Step-by-step explanation:
The correct answer is b. Communities, community ecology, evolution.
At different levels of scale in ecology, different disciplines and focal areas are studied. At the community level, the focus is on studying the interactions between different species within a particular area. This includes studying how these interactions influence the evolution of species over time. Therefore, option b accurately describes the relationship between the level of scale and the related discipline and focal area.
