| Biome | A region of land with characteristic climate, soil and organisms. |
| Weather | Describes the conditions of the atmosphere in a certain area for a short period of time. Weather changes constantly. |

| Food Chain | A sequence of feeding relationships among living organisms, as they pass on food energy. |
| Energy Flow | The movement of energy, which originally comes from the sun, from one organism to another. |
| Food Web | The network of feeding relationships among organisms. |
| Symbiosis | An interaction between two organisms of different species living in close proximity that lasts over time. |
| Parasitism | A symbiotic relationship in which one of the partners is harmed and the other benefits. |
| Mutualism | A symbiotic relationship in which both partners benefit. |
| Commensalism | A symbiotic relationship in which one partner benefits and the other is indifferent. |
