Explanation
A food chain is the sequence through which food energy passes from one organism to another — producer to herbivore to carnivore to decomposer. It is the standard ecological definition (NCERT Class 10/12). The other options describe nutrient cycling, food webs and unrelated concepts. Hence passage of food from one organism to another.
