The dynamics of the human population in Oshawa are influenced by the carrying capacity.

• When the population is below the carrying capacity, the birth rate exceeds the death rate, leading to population growth.

• At the carrying capacity, the birth rate equals the death rate, and the population stabilizes.

• If the population exceeds the carrying capacity, the death rate surpasses the birth rate, causing a population decline.

This model demonstrates how population growth is controlled by the availability of resources and space.

People (Human): Used for stocks like population and carrying capacity. It represents the number of individual humans.

People per person per year (Human / Human / Year): Used for rates like birth and death rates, indicating the number of people added or subtracted per person in the population each year.

People per year (Human / Year): Used for flows like population change, representing the total number of people added or subtracted from the population annually.

The dynamics of a moose population with density-dependent birth rate...the birth rate equals the death rate when the population is at carrying capacity; the birth rate is greater than the death rate when the population is below carrying capacity; the birth rate is below the death rate when the population is above carrying capacity.

The following model shows us the fictional city in Ontario a municipality called Omnicity with fictional energy values and the relationship between all the energy types used within the city, how it affects the energy grid, with the inflows from the various types of energy the city produces. The power usage coming from Businesses and Residential, whilst the energy produced comes from Wind, Solar, Hydro, Nuclear, Natural Gas, and Micro-generated Solar Electricity from residential housing.

This model stimulates the growth of the human population at a large scale, ranging from global to local growth. It is modeled using logistic growth, where the carrying capacity (maximum sustainable population) limits the exponential growth due to available resources.

This system diagram represents population levels for humans ranging from the world population level down to the Oshawa population level. This diagram consists of stocks which represent World, Canada, Ontario, Durham Region, and Oshawa in terms of number of people. The flows in the diagram represent the movement of people between the population levels in terms of people per year.

This model displays how the population of the Earth changes. With a larger birth rate than death rate the population increases and heads towards K (carrying capacity). If the birth rate is lower than the death rate, the population will slowly diminish and will move away from carrying capacity.

The dynamics of Oshawa’s population are modeled with a carrying capacity, where population growth is influenced by density-dependent factors. At lower population sizes, the birth rate exceeds the death rate, with a maximum birth rate and a maximum death rate. As the population increases and approaches the carrying capacity, resource limitations cause the birth rate and death rate to equalize. If the population exceeds the carrying capacity, the death rate will surpass the birth rate, gradually reducing population size, stabilizing near equilibrium.

The model shows the change of Pickering's population by using birth rate, death rate and also how many people move in and out of the city. The population stock shows the number of residents and the flows are based on people per year. The model assumes that as the population grows and housing becomes more limited, the rate at which people move in decreases. Every data value that I entered aside from the population is my own assumption.
