Answer 1

A food chain is a model that shows specifically how energy moves through living things, illustrating the direct feeding relationships between organisms in an ecosystem. In a food chain, energy is transferred from one organism to another, typically starting from producers (like plants) and moving up to various levels of consumers (like herbivores and carnivores).

So, the best definition among the options provided is: **A model that shows specifically how energy moves through living things.**
