Final answer:

Food chains and food webs show energy flow in ecosystems, while energy pyramids demonstrate energy distribution among trophic levels.


Explanation:

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.
