Question

can someone please help answer this?

Based on the figure above, when is the per capita growth rate (per capita rate of increase, or r) the highest? or remains constant over the 120 years O Si Around years 18, when the slope of the curve is at its steepest O prin years 20-30, when curve goes from being almost vertical to horizontal Or is consistently high from years 0-1852

the figure is shown below

Answer 1

Answer-

The per capita growth rate is highest b) around years 18, when the slope of the curve is at its steepest.

The logistic growth occurs where there are limited resources. The upper boundary for the population size is known as the carrying capacity (K). Here carrying capacity, K is around 150. At the very beginning the population size is very small and so is growth rate. But after some time, population starts growing at a rapid pace. Population reaches its carrying capacity after 20 years and from this time there is almost zero growth because of shortage of space and resources. But absolute growth is greatest when number of individuals in population, N = K/2 or 150/2 = 75. This population size is reached at around year 18. At this time growth curve is steepest as the population has enough resources and reproductive fitness.
