In growth pattern, (1 – N/K) is

Environmental resistance is the sum of environmental conditions (such as drought, mineral deficiency, and competition) that tend to limit an organism's or kind of organism's biotic potential and place a numerical limit on its growth. Because the amount of the above components is dependent on the population size, it is a density dependent population control. The environmental resistance is represented by the quantity '(K-N)/K' in the logistic population growth equation, where K is the carrying capacity and N is the number of persons in a population over time.

Carrying capacity represent the average population in particular habitat and represented by K.

Intrinsic rate of natural increase represent the difference between rate of birth and rate of death in particular year.

Biotic potential represent the maximum growth of an organism.
