Flux modeling is a research area within the field of ecological or environmental science that focuses on quantifying the flow of energy or materials through ecosystems. This includes the movement of nutrients, pollutants, gases, and other substances within and between various components of an ecosystem, such as plants, soil, water, and the atmosphere. Flux modeling aims to understand and predict how these flows influence ecosystem functioning, sustainability, and resilience. This research often involves the use of mathematical and computer models to simulate and analyze these fluxes and their impacts on ecosystems.
