Food Web
What is Food Web?
A network of interconnected food chains showing all the feeding relationships in an ecosystem. Because most organisms eat more than one kind of food and are eaten by more than one predator, a food web represents the real pattern of energy and material transfer far better than a single chain does. Tracing the arrows into and out of one organism reveals its food sources, its predators and its competitors, which is what makes it possible to predict the effect of a change in one population.
This definition is part of the Relationships of Organisms with One Another and with the Environment chapter in Cambridge O Level Biology.
