Explain why a food web is a more realistic model of
energy flow than a food chain.

Food chain only shows one path by which energy can move through an ecosystem, because most organisms eat a variety of things, they are part of many food chains. A food web shows multiple pathways of energy, it shows interconnected food chains in a ecosystem.

Hope this helps

Yeah
