Question

Quizplus · Accepted Answer

Ecological communities do not always have clear-cut boundaries, making it difficult to define them. Other factors like species composition, diversity, and interactions among species are also important in defining a community. The other options are incorrect because biomass, energy distribution, and number of species can all be studied in an ecological community, and there is no set size for a community.
