Question

Among all the assumptions for the exponential growth model, which no longer hold true for

the age-structured model?

Answer 1

Ans:

Population growth is mean as group of organism interacting with the same species and includes at all stages or ages.

During the birth rate and death rate become equal , so the population growth is being stop and age of equal.

Which is identified the number of individuals of each individual age by using demographic structure of population, population size, population density, and it's geographical range.

Exponential population growth

In this case , the way of population growth is with assumption of that every individual produces two offspring during lifetime,and then dies, while that generated double the population size ( total number of individuals) of each generation.

Due to the birth and death rate each a time points do not various or change over time for growth rate of population.

The growth rate is the intrinsic value of natural increase it called r, for the population of size N. And the birth rate b - death rate d of population.

By the equatioequation

dN/dt = rN

By the growth pattern over time t show that population size times the growth rate leads the changes in population size with time.

During this r value is fixed along with time and the population does not grow linearly in this age structure model because the every individual birth with generation reproducing.

The results the population showing the size in its very quickly, the model predicts the exponential growth equation with natural population size limits done by the environment biological factors.
