Apr 5, 2024 · 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.
In ecology, a food chain is a series of organisms that eat one another so that energy and nutrients flow from one to the next. For example, if you had a hamburger for lunch, you might be part of a food chain that looks like this: grass → cow → human.

Nov 21, 2022 · 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.
- Definition of Food Chain. A food chain shows energy pathways in ecosystems. Each ecosystem on the planet has food chains of organisms ranging from producers to consumers.
- Food Chains and Food Webs. Food chains differ from food webs in that they are showing a single line of feeding relationships. Food webs actually consist of many food chains together.
- Definition of Trophic Levels. A trophic level is a step in the food chain that each organism occupies. In a simple food chain, it is easy to see the trophic pyramid.
- General Food Chain Types. Most food chains consist of at least producers and primary consumers. Some chains are more complex and have secondary consumers and tertiary consumers.
Food Webs. A food web represents multiple pathways through which energy and matter flow through an ecosystem. It includes many intersecting food chains. It demonstrates that most organisms eat, and are eaten, by more than one species. Examples are shown in Figures below and below. Food Web. This food web consists of several different food chains.
Jul 31, 2022 · For example, in a meadow ecosystem, plants may support a grazing food web of different organisms, primary and other levels of consumers, while at the same time supporting a detrital food web of bacteria, fungi, and detrivorous invertebrates feeding off dead plants and animals.
