I choose population growth model as this equition:
(1)
It describe how the number of individuals in a population, N, varies with time. Here the first term aN corresponds to the birth of new member, while the second term corresponds to deaths. The death term is proportional to to allow for the fact that food will becomeharder to find when the population N becomes larger.
We could solving (1) with using the Eular method.
And we can get :
Then we could use the python code to get the figure of the model.
