A food web is a detailed interconnecting diagram that shows the overall food relationships between organisms in a particular environment. The simplest explanation is that food webs are "who...
Food web, a complex network of interconnecting and overlapping food chains showing feeding relationships within a community. 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.
Each living organism is part of multiple food chains that shows a possible path that energy and nutrients follow as they move through the ecosystem. Food Web. Previously known as the food cycle, the food web model was developed by Charles Elton in his book Animal Ecology in 1927.
The fundamental purpose of food webs is to describe feeding relationship among species in a community. Food webs can be constructed to describe the species interactions.
A food web is a graphic representation of a holistic, nonlinear web of primary producers, primary consumers, and higher-level consumers used to describe ecosystem structure and dynamics (Figure 1). Figure 1. Example of simplified food chains (a) and food webs (b) of terrestrial and marine ecosystems.
A food web consists of all the food chains in a single ecosystem. Each living thing in an ecosystem is part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community. Position in the food web, or trophic level, is used in ecology to broadly classify organisms as autotrophs or heterotrophs.
