This model represents a population with a density-dependent birth rate for the population of the town of Whitby. The birth rate and death rate for the town of Whitby will be equal if the population in this model reaches its carrying capacity (K). When the town of Whitby's population exceeds its carrying capacity, that means that the death rate has exceeded the birth rate. The opposite occurs when the population is below its carrying capacity, which in this case, the birth rate has exceeded the death rate for this population. This model aims to demonstrate what happens to the current population of Whitby when it reaches its carrying capacity (K).
