A food chain shows how energy passes from one living thing to another in an ecosystem. It starts with producers, like plants, that make their own food using sunlight. Then come consumers, which eat other organisms. Primary consumers eat producers, secondary consumers eat primary consumers, and so on. Decomposers break down dead organisms, returning nutrients to the soil.
Imagine a simple food chain: grass $\rightarrow$ grasshopper $\rightarrow$ frog $\rightarrow$ snake $\rightarrow$ hawk. Each arrow shows the flow of energy. πΏ
