If biotic potential is higher than environmental resistance, the population will (increase or decrease) increase. An organism’s rate of reproduction and the size of each litter are the primary determining factors for biotic potential.

Our Population DVD initially looks at how population growth rates are calculated and introduces the concepts of biotic potential, exponential growth and environmental resistance before looking at boom-and-bust cycles and the carrying capacity of ecosystems. On the other hand, climatic conditions (lack of space, light), fire and temperature are several abiotic factors that limit biotic potential. Full expression of the biotic potential of an organism is restricted by environmental resistance, any condition that inhibits the increase in number of the population. Environmental resistance can restrict the full expression of the biotic potential of a population by preventing the increment of the individuals of the population. /Creator (�� w k h t m l t o p d f 0 .
