The correct answer is **D**: a food chain represents one possible pathway that energy and matter can take in an ecosystem; a food web contains multiple interconnected food chains.
### Explanation:
- A **food chain** is a linear sequence that shows how energy and nutrients flow from one organism to another, typically starting with producers and moving through various levels of consumers (herbivores, carnivores, etc.). It represents only one specific pathway of energy transfer.
- A **food web**, on the other hand, is a more complex diagram that illustrates how multiple food chains are interconnected within an ecosystem. It accounts for the various ways that organisms interact and shows the various pathways through which energy and matter flow. Hence, it includes multiple feeding relationships among different species.
