Final answer:
Food webs provide a more accurate depiction of ecosystem interactions than food chains, showing the multiple feeding relationships and trophic levels each organism is part of.
Step-by-step explanation:
Food webs are more realistic than food chains because they represent the complex network of feeding relationships in an ecosystem. Unlike food chains, which show a single pathway of energy flow, food webs illustrate many intersecting food chains and demonstrate the multiple connections each organism has as both a predator and prey. For instance, a grasshopper in a terrestrial food web may only eat plants, but it can be a food source for spiders, mice, birds, and frogs, showing its involvement in various trophic levels.
