Zedler, editors, Foundations of Restoration Ecology (Science and Practice of Ecological Restoration), Washington, D.C.: Island Press, ISBN 978-1-59726-016-9, page 165:
      No species exists in a vacuum. Rather, each species is embedded within a network of predator-prey interactions in what Charles Darwin referred to as an “entangled bank” and is now known in the most general sense as a food web. In its most basic form, a food web reveals to us something about the feeding relationships in a system. More broadly, food webs represent a way of thinking about an ecological system that considers trophic (consumer-resource) interactions among species or groups of similar species (trophic guilds or trophic levels).
