Understanding Food Webs

Food webs provide a network-based perspective on ecological interactions by illustrating who consumes whom within an ecosystem. They offer a comprehensive framework that emphasizes the interconnected relationships between various species beyond simply studying isolated organisms or interactions. The importance of food webs lies in their ability to capture the complexity of ecosystems, revealing how these relationships contribute to ecological resilience and stability. Jennifer Dunn's work demonstrates the dynamic nature of food webs, seeking to understand how these networks evolve and respond to both environmental changes and human influences.
