| producer | uses energy from the sun |
| consumers | take in energy when they eat plants or animals |

| food chain | a simple way of showing how energy, in the form of food, is passed from one organism to another |

| ecological pyramid | models the number of organisms at each level of food chain |
| bottom level of the ecological pyramid | represents the producers |
| the rest of the levels of the ecological pyramid | represents the consumers |
| energy pyramid | compares the level of energy available at each level of the ecosystem |
| How is energy available as food renewed? | by plants using sunlight |
| water cycle | involves the processes of evaporation, condensation, and precipatation |
| What do you have in common with all organisms? | contain carbon |
| carbon cycle | movement of carbon through Earth's bioshpere |
| examples of producers | trees, grass, and green algae |
| Which level of the food chain has the most energy? | producers |
