d) competition

influences an individuals probability of survival and reproduction in a manner that depends on the size of the population

states that two species competing for the same limiting resource cannot coexist

incorporates all of the populations of organisms within a given area

d) exponential growth rate

a species that plays a role in its community
a) k - selected species
