Food Web
A food web is a network of many interconnected food chains in an ecosystem.
Practice This ConceptMain explanation
Teacher explanation
Most organisms do not depend on only one food source. A food web shows several feeding links together, so it reflects nature more realistically than a single chain. If one organism becomes fewer in number, other feeding paths may still support the ecosystem for some time.
Example
In a garden, a grasshopper may be eaten by a frog or a bird, while a rabbit may eat grass and also be prey for a fox. These links form a food web.
Simple analogy
A chain is one line, but a web has many crossing lines.
Common confusion
Students often think a food web is just a longer food chain. In reality, it is a network with many connections.
Exam tip
Use the word network or interconnected food chains when explaining a food web.
