The formula for exponential population growth is-
1 $\mathrm{dt} / \mathrm{dN}=\mathrm{rN}$
2 $\mathrm{dN} / \mathrm{rN}=\mathrm{dt}$
3 $\mathrm{rN} / \mathrm{dN}=\mathrm{dt}$
4 $\mathrm{dN} / \mathrm{dt}=\mathrm{rN}$
Explanation:
J-Shaped form of population growth is mathematically described by an equation of exponential or geometric increase, which is as follows : $\frac{\mathrm{dN}}{\mathrm{dt}}=\mathrm{rN}$ Where, $\begin{aligned} & d=\text { Rate of change } \\ & t=\text { time } \\ & \mathrm{N}=\text { Population size } \\ & \mathrm{r}=\text { Biotic potential of each individual }\end{aligned}$

The growth curve of bacterial population in lab is plotted against time. What will be the shape of graph?
1 Sigmoid
2 Hyperbolic
3 Ascending straight line
4 Descending straight line
Explanation:
Under continuous supply of food and space in the laboratory conditions the bacterial population grows exponentially and shows a $\mathbf{J}$-shaped curve, thus the curve would be hyperbolic. - Exponential growth such populations ultimately crash when the population size grows beyond carrying capacity.

In an area, a population with large size individuals having long life span, more parental care and slow development was present. The type of population growth curve will be
1 S-shaped
2 J-shaped
3 Z-shaped
4 All of these
Explanation:
The population growth curve will be Sshaped or sigmoid or logistic. The growth curve has five phases: Lag phase, Positive acceleration phase, Exponential phase, Negative acceleration phase and Stationary phase. Most of the organisms including human population shows S-shaped curve.
