When many such individual food chains occur in an ecosystem, it is known as Food Web. A food chain shows how matter and energy from food are transferred from one organism to another, whereas a food web illustrates how food chains intertwine in an ecosystem.

Like other food chains, desert food chains also start with producers making their food.That is, they can form one of the links in a food chain. It demonstrates . It also implies the . The organisms are joined by arrows which show the transfer of energy in . For example, in the meadow ecosystem shown below, there is a grazing food . Antarctica has marine ecosystems and terrestrial (land-based) ecosystems. The ecosystem has been a key organizational concept in ecology for many years, an important theoretical and applied concept for studying global change, and human environmental impacts. that shows their feeding relationship, i.food web, a complex network of interconnecting and overlapping food chains showing feeding relationships within a community.
