Today we have a mcq question which is the exponential model of population growth assumes the death rate declines as population density increases per capita growth rate does not change.
00:17
Industrialization causes a fall in the birth rates.
00:20
Resources are limited, right? so, you know, the per capita birth rate is, you know, it's a total number of offspring are born to the population in the area divided by the population in the area, right? similarly, per capita death rate is total number of individuals died in the population in the area, divided by the population in the area.
00:50
So, subtracting per capita death rate from the per capita birth rate, per capita growth rate is obtained, right? in exponential model of population growth per capita growth rate is constant.
01:05
It is necessary that the resources are unlimited.
01:09
So option b per capita growth rate does not change will be the correct answer.
01:18
Right? so when density of population increases, resources become limited.
01:26
There will be more struggle for existence.

Population growth declassion...
