Answer -
If adequate quantity of food resources are available to individuals in a population, it grows exponentially. The integral form of exponential growth equation can be used to estimate the exponential growth, which is as follows:
Nt = No ert ————–equation (1)
Where, Nt is the populationdensity after ‘t’ time
No is the population densityat time zero
e is the base of natural logarithm = 2.71828
r is the intrinsic rate of natural increase
Let the current population density be ‘x’
∴ The population density after two years will be 2x and t givenis 3 years
Substituting these values in equation (1)
Therefore, the intrinsic rate of naturalincrease of the population is 0.2311
