The links in a food chain
A food chain shows how energy passes from one living thing to the next, starting with the sun. Here is what happens at each labeled part of the diagram:
| Link | What it does |
|---|---|
| Sun | The original source of energy for almost every food chain. |
| Producer | A plant, such as grass, that makes its own food from sunlight. |
| Primary consumer | An animal that eats producers — usually a plant-eater (herbivore). |
| Secondary consumer | An animal that eats the primary consumer. |
| Tertiary consumer | An animal that eats the secondary consumer. |
| Apex predator | A top predator at the end of the chain that nothing else hunts. |
