When the population is small,the R.G.R is almost constant.What do u understand by the term R.G.R?

Question

The population of Aedes mosquitoes which carry the Dengue virus can be modeled by a differential equation which describes the rate of growth of the population. The population growth rate dP/dt is given by dP/dt = rP(1-P/k) , where r is a positive constant and k is the carrying capacity.

Answer 1

RGR is the relative growth rate. When r is small and the population is small, the growth rate is small (slow), but is gradually increasing until the carrying capacity is reached.
