Answer & Solution
Correct answer: B. A single line of feeding links
1. A food chain is a linear sequence through which energy and nutrients pass.
2. There is a single path from producers up through the consumers.
3. Each organism along it occupies a trophic level.
4. A branching arrangement with many links is a food web, which is a different model.
