Food webs represent complex networks of ecological interactions among organisms, illustrating how energy and nutrients flow through an ecosystem. These webs highlight relationships such as predator-prey dynamics, competition, and symbiosis, showcasing the interconnectedness of species. Understanding food webs is crucial for comprehending ecosystem health and stability, as disruptions to one part of the web can have cascading effects throughout the system. By analyzing these interactions, ecologists can better understand ecological balance and inform conservation strategies.
