Multiple Choice

Which of the following best describes the difference between a food chain and a food web?

A food chain includes only herbivores, while a food web includes both herbivores and carnivores.

A food chain shows a single linear path of energy flow, while a food web shows multiple interconnected paths.

A food chain represents energy flow in aquatic ecosystems, while a food web represents energy flow in terrestrial ecosystems.

A food chain is a complex network of feeding relationships, while a food web is a simple linear sequence.

Verified step by step guidance

Identify the key terms: 'food chain' and 'food web'. Understand that a food chain is a linear sequence of organisms where each is eaten by the next member in the chain.

Recognize that a food web is a more complex network of multiple food chains that are interconnected, showing how different chains overlap and interact.

Consider the options given: The first option incorrectly states that a food chain includes only herbivores, which is not true as it includes various trophic levels.

Evaluate the second option: It correctly describes a food chain as a single linear path of energy flow and a food web as multiple interconnected paths, which aligns with the definitions.

Review the remaining options: The third option incorrectly associates food chains and webs with specific ecosystems, and the fourth option reverses the complexity of food chains and webs.
