A food web (or food cycle) is the natural interconnection of food chains and a graphical representation (usually an image) of what-eats-what in an ecological. Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem. Food web is a connection of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web. Producers, or autotrophs, make their own organic molecules.
