Further, round patterns of ecology like equitability, food web, productivity, and species splendour and community assembly are considered in modern study of communities in ecology.Background History. In a community, species interact in different ways. There has been a cleavage on how community works in the field of ecology. There are different biotic and abiotic factors that imply the way species in a community interact.
