Using the adsorbtion theory of chemical kinetics, the rate of growth of a single population is expressed as.where X is population density, Xm is the maximum population density permitted by the supply of a limiting resource and Xm' is a parameter which expresses the efficiency of utilisation, or uptake, of the resource. If the equation reduces to an exponential or logistic form.μc is a parameter, in units of t-l, concerning the velocity of population increment. Its value is intermediate between the value for...
