Ecosystem functioning is a field of research that focuses on understanding how interactions between organisms and their environments contribute to the overall functioning of ecosystems. This includes studying processes such as nutrient cycling, energy flow, and primary productivity, as well as the roles of species diversity, community composition, and ecosystem resilience in maintaining ecosystem health and stability. Researchers in this area may use experimental manipulations, field observations, and mathematical modeling to investigate how different factors influence ecosystem processes and dynamics. Ultimately, the goal of ecosystem functioning research is to better understand and conserve the complex interactions that drive ecological systems.
