The correct food chain is "mouse > snake > corn," representing the natural flow of energy in an ecological system where mice consume corn, snakes prey on mice, and energy transfers through this sequence.
The correct food chain among the options is "mouse > snake > corn." This sequence accurately represents the flow of energy in an ecological system. In this scenario, mice primarily consume corn or grains, making them herbivores. Snakes, in turn, prey on mice as carnivores. The energy transfer follows the natural order of a food chain, with energy moving from the primary producer (corn) to the primary consumer (mouse) and then to the secondary consumer (snake). The other options present incorrect sequences: "corn < mouse < snake" and "mouse > grass > snake" don't align with typical ecological relationships, and "snake > mouse > corn" reverses the flow of energy, deviating from the usual progression in a food chain.
