How does a food web differ from a food chain?

A food web is best characterized as a complex network of interrelated food chains, which illustrates the multiple pathways through which energy and nutrients flow within an ecosystem. In contrast to a food chain, which depicts a simplistic and linear progression of energy transfer from one trophic level to the next, a food web illustrates the interconnections between various species and highlights how they can consume or be consumed by multiple organisms. This complexity provides a more accurate representation of real-life ecosystems, where organisms often have diverse diets and interactions with several different species.

Understanding the interrelatedness of these food chains within a food web underscores its importance in maintaining ecological balance, demonstrating how the removal or addition of a single species can impact the entire system. This complexity is vital for ecosystem stability, resilience, and the transfer of energy among all levels of participants within the ecological framework.
