The three terms "food chain", "foodweb", and "food cycle" are nearly interchangeable, although food chains are usually simpler representations, lacking omnivory and other complications of real systems. Oversimplification is a common criticism of food chains, but also of foodwebs and food cycles....

Most organisms can eat, and be eaten, by many different animals. A food chain wouldn’t be able to show this. Food webs show all these connections. They are more complicated but more accurate. In the African savannah food web shown here, we can see multiple arrows pointing to different ...

Many current ecological problems involve human disturbances of both food webs and the nutrients that cycle through them. Little progress can be made towards elucidating the complex feedback relations inherent in the study of nutrient cycles in ecological systems without the tools of mathematics and ...
Herbivorous animals acquire some of the stored energy by eating the plants; those animals in turn serve as food for, and so pass the energy to, predatory animals. Such sequences, called food chains, overlap at many points, forming so-called food webs. For example, insects are food for ...

The concept of the food web was initially described as food cycles in 1927, which was later changed to the food web in the subsequent text. Food webs are representations of real ecosystems where different living organisms are aggregated into trophic levels to generate a relationship. ...
to 4 or 5 links and the food chains were not isolated, but hooked together into food webs (which he called "food cycles"). The feeding interactions represented by the food web may have profound effects on species richness of community, and ecosystem productivity and stability (Ricklefs 2008)...
