Food Chains and Food Webs
Food chains and webs are diagrams that show the flow of energy through an ecosystem. We can see the relationships between the organisms and how they rely on each other for survival.
Food Chains
Food chains are diagrams scientists use to show how energy and nutrients pass from one organism to another in an ecosystem. Arrows show the path energy takes.

Food Webs
Food webs are diagrams that show how different food chains in a community are linked together.
**All parts are important if part is removed.**
This web serves as a model for feeding relationships within a community. Members of a species may occupy different positions during their lives.
A food chain shows one path that the energy flows. A food web shows all the food chains and all of the organisms in a community.
