A food web just extends the food chain to make it more complex. Most species feed on more than one other species as are fed on by multiple other species. This is what the food web helps show better than the food chain. Definition - ecology a community of organisms where there are several interrelated food chains. The food web is divided into two broad categories: the grazing web, which typically begins with green plants, algae, or photosynthesizing plankton, and the detrital web, which begins with organic debris. The earliest food webs were published by Victor Summer hayes and Charls Elton in 1923 and Hardy in 1924. That was over 80 years ago. Food webs can be on land or underwater and sometimes they cross over. For example a polar bear eats fish which are under the water.
