|  |   According to Park economic  competition was a special case of the struggle  for survival (Charles Darwin On the  Origin of Species 1859). Park considered the city as a social organism  with distinct parts bound together by internal processes. Urban life was not  chaos and disorder but rather tended toward an ‘orderly and typical grouping of  its population and institutions’. Urban life according to Park was organized at  two distinct levels—Biotic and cultural. The biotic or symbiotic  society is based on competition and  cultural society is based on communication  and consensus. Park argues that these two are dependent on one another. In  actuality, it is a complex relationship. The competition at the biotic level is more restricted in society due  to the existence of conventions, mores,  law.1
