Which statement best describes the difference between the theoretical concept of a community and the ways in which communities are delineated in practice? in theory, communities can be defined by physical or biological characteristics, but in practice, these characteristics are difficult to measure and are not used. In theory, a community is defined only by abiotic factors of the area; in practice, communities are delineated by biological attributes as well. In theory, communities consist of ...
