Question

what is intrinsic growth?​

Answer 1

The rate at which a population increases in size if there are no density-dependent forces regulating the population is known as the intrinsic rate of increase. It is
{\displaystyle {\dfrac {dN}{dt}}{\dfrac {1}{N}}=r}
where the derivative {\displaystyle dN/dt is the rate of increase of the population, N is the population size, and r is the intrinsic rate of increase. Thus r is the maximum theoretical rate of increase of a population per individual – that is, the maximum population growth rate. The concept is commonly used in insect population biology to determine how environmental factors affect the rate at which pest populations increase. See also exponential population growth and logistic population growth.

Answer 2

Intrensic growth is the growth in size of population between good time intervals and no influence of any external factors like population density is called intrensic growth.

The rate at which natural growth of population occurs in intrensic method is called intrensic growth rate.

It is calculated by formula

dN / dt ×1 / N = r

Where dN / dt is the rate of increase in population

N is population size

r is maximum theoretical rate of increase in population
