Question

2. Describe the growth of the hypothetical population shown in the graph,

Answer 1

The growth of the population is described below.

Explanation:

The population growth of the region is varying according to many factors like,

A. Members of the reproductive age group.

B. Availability of nutrition.

C. Mortality rate of the population.

Here the members of the reproductive age group are few. The population being small in a large area there is a high availability of nutrients.

So the growth rate of the population will be very high. This is called the log phase of the growth.

Then comes the lag phase of growth where the population is considerably big with a fight for food and shelter. The survival of the fittest is seen and the population still grows but slowly. This is the lag phase.

But with time, the population growth is stopped because the ecosystem has a particular carrying capacity which is the maximum number of population that the ecosystem can support. So beyond this, the population won't increase, and thereby the natality rate and the mortality rate becomes equal.
