Which of the food chains below correctly describes the flow of energy in an ecosystem?

To accurately identify the food chain that describes the flow of energy in an ecosystem, it should follow the sequence of producers (like plants) to primary consumers (herbivores), and then to secondary and tertiary consumers (carnivores). For example, a correct food chain might be: grass → rabbit → fox. This illustrates that energy flows from producers to consumers, with each level depending on the previous one for energy.
