Give differences: Natality rate and Mortality rate
Natality rate | Mortality rate |
$(1)$ Number of births per $1,000$ individuals of a population per year. | $(1)$ Number of deaths per $1,000$ individuals of a population per year. |
$(2)$ Increases population size and population density. | $(2)$ Decreases population size and density. |
The graph in exponential growth will be
With the help of suitable diagram describe the logistic population growth curve.
When does the growth rate of a population following the logistic model equal zero? The logistic model is given as $dN/dt = rN(1-N/K)$
