Answer 2

[AI-generated answer — Step-by-Step Bot]

The correct response is: A food chain represents one possible pathway that energy and matter can take in an ecosystem, while a food web contains multiple, interconnected food chains. In a food chain, energy and matter flow in a linear sequence from one organism to another, starting with a producer (usually a plant) and ending with a top predator. However, in a food web, multiple food chains are interconnected, showing the relationships between multiple organisms in an ecosystem. It includes producers, primary consumers, secondary consumers, tertiary consumers, and decomposers. Additionally, while a food chain may only include specific types of organisms (such as herbivores), a food web includes a variety of organisms, including herbivores, carnivores, and omnivores.
