of factors that can contribute to the growth of a population and these trends can be seen in a number of species. It is generally believed‚ from an ecological perspective‚ that populations will display either an exponential of logistic growth rate. If optimal environments are consistently maintained with no biotic or abiotic limiting factors (excess food‚ excess space availability‚ optimum climactic environment‚ no predation‚ etc) then a population will grow in an exponential direction.
