Concept:A food chain describes the linear sequence of organisms where each organism eats the one below it, transferring energy through food.Explanation:The term “food chain” refers to the unidirectional flow of energy from producers (plants) to consumers and then to decomposers.Each step in this sequence is called a trophic level.Energy is lost at each level, so only about 10% passes to the next.Thus, the correct definition is the passage of food (and the energy it contains) from one organism to another.
Answer:Option C: passage of food (and thus energy) from one organism to another.
