Food chains and food webs show energy flow in ecosystems, while energy pyramids demonstrate energy distribution among trophic levels.
Food webs and food chains are both models that show the flow of energy through ecosystems, but they have key differences. Food chains depict a single pathway of energy flow, while food webs illustrate multiple interconnected chains. In a pyramid of energy, if the first trophic level has 100 units of energy, the primary consumers at the next level would have 10 units of energy available.
