| photosynthesis | The process when a plant uses sunlight to make sugar molecules |
| energy | This is transferred from one trophic level to another as organisms consume others. |
| food chain | The energy flow from one trophic level to another. |
| decomposers | These consumers absorb any dead material & break it down into simple nutrients. |
| producer or autotroph | This makes its own food through photosysthesis. |
| consumer or heterotroph | This gets energy by eating other organisms. |
| nitrogen fixation | The process in which certain bacteria convert nitrogen gas to ammonia. |
| Deforestation, industrialization, & population growth | This is a result of humans. |

| carnivore | This consumer only eats other consumers. |
| omnivore | This consumers eats other consumers AND producers |
| autotrophs | self-feeders or producers who make their own food. |
| heterotrophs | These consumers get their energy by eating other organisms. |
| trophic level | When energy moves from one organism to another when it is eaten. |
| food web | When multip0le food chains are linked together. |
