179. (d) summarize a number of scientific theories that attempt to explain why animal populations do not exceed certain limits (Because the author has been telling about various regulators which control population growth)
180. (d) make sufficiently accurate predictions about the effects of crowding (Because the third para suggests that "One challenge for density-dependent theorists is to develop models that would allow the precise prediction of the effects of crowding")
181. (a) As the number of foxes in Minnesota decrease, the growth rate of this population of foxes begins to increase (Because "the population growth is primarily density-dependent—that is, the rate of growth of a population in a region decreases as the number of animals increases" and so is the revers true)
182. (d) regulating sexual activity (Because "such codes provide organisms with information on population size in a region so that they can, if necessary, exercise reproductive restraint.")
183. (b) qualified acceptance (Because it "has been challenged, with some justification, by several studies")
184. (c) The results of one study, for instance, have suggested that group vocalizing is more often used to defend territory than to provide information about population density (Because Wynne-Edwards’ theory, linking animal social behavior and population control" has been challenged so the continuation would be to give some other reason for "group vocalizing")
