Population growth

About this model

This diagram represents a complex simulation of a population's growth and decline in response to food production and consumption dynamics. Assets such as farms and the environment are modeled to produce food at varying rates, contributing to a central food storage. The stored food is then consumed by the population, represented as another key component in the ecosystem. The system intricately connects food production from multiple sources to population growth, showcasing the delicate balance between resource availability and population needs.

At its core, the diagram simulates how population size fluctuates based on the intricate balance between food production (from farms and environmental harvesting) and food consumption. Registers calculate key variables such as food produced by farming and hunting, population growth, and food consumption per capita. These variables guide the flow of resources (food) to storage and from there to consumption, impacted by factors such as hunting efficiency and per capita consumption rates. Drains represent food consumption and potential population decline due to insufficient resources, emphasizing the critical role of sustainable practices and resource management in maintaining population health and growth.
