Ecotone is a place where two or more different biomes or ecosystems meet, and there is a gradual transition between them. The distinct plant communities found in adjacent areas support the holistic concept of communities because they show that the communities in the area are influenced by the interaction of different ecological factors. The abrupt change in environment that occurs in an ecotone is not significant in determining the makeup and functioning of communities, but it is the interactions between different ecological factors that affect the communities. Therefore, option B is the correct answer.
