food webs provide a framework within which a complex network of predator–prey interactions can be organised. a food web model is a network of food chains. each food chain starts with a primary producer or autotroph, an organism, such as a plant, which is able to manufacture its own food. next in the chain is an organism that feeds on the primary producer, and the chain continues in this way as a string of successive predators. the organisms in each chain are grouped into trophic levels, based on how many links they are removed from the primary producers. the length of the chain, or trophic level, is a measure of the number of species encountered as energy or nutrients move from plants to top predators. food energy flows from one organism to the next and to the next and so on, with some energy being lost at each level. at a given trophic level there may be one species or a group of species with the same predators and prey.
