Which best defines a food web?

A food web is best defined as a complex network of feeding interactions within an ecosystem. This intricacy arises because most organisms do not rely on a single food source; instead, they may eat multiple types of organisms, and a variety of other organisms may prey upon them. This interconnectedness illustrates how energy and nutrients flow through an ecosystem, demonstrating the relationships among producers, consumers, and decomposers.

While a food web does include predator-prey relationships, focusing solely on these interactions simplifies the complexity of the network and overlooks the various levels of consumers and the role of decomposers. It is a more comprehensive representation of different species and how they interact across various trophic levels. This complexity allows for a better understanding of ecosystem dynamics, resilience, and stability, as it captures the interconnected dependencies that exist in the natural world.
