Which of the following statements best explains why a food web is more realistic than a food chain in representing ecological relationships?

• A. A food web is simpler and easier to understand than a food chain.
• B. A food web includes abiotic factors, while a food chain includes only biotic factors.
• C. A food web focuses solely on predator-prey relationships, while a food chain includes all types of interactions.

Answer: (D)

Verified step by step guidance

1. Understand the concept of a food chain: A food chain is a linear sequence of organisms where nutrients and energy pass as one organism eats another.
2. Understand the concept of a food web: A food web is a complex network of interconnected food chains in an ecosystem, showing multiple pathways through which energy and nutrients flow.
3. Compare the two concepts: A food chain represents a single pathway of energy flow, while a food web illustrates multiple pathways, reflecting the complexity of real ecosystems.
4. Evaluate the given statements: Analyze each statement to determine which one accurately describes the difference between a food web and a food chain.
5. Identify the correct explanation: The statement 'A food web shows multiple pathways of energy flow, while a food chain shows only a single pathway' best captures the realistic representation of ecological relationships in a food web.
