| Ecology | How organisms fit into their environment |
| orgnanisms & their Ecosystems | Ecosystems are self=sustaining collictions of organisms and their physical environment |
| Community | where organisms live |
| Habitat | Physical loction of a community |
| Niche | an organism's professon, the sum of its interactions with its environment |
| producers | most are photosynthetic(capturing the sun's energy) |
| Consumers | eat other organisms to obtain energy |
| Decomposers | consume organic waste |
| How energy flows | energy flows through the ecosystem by trophic levels |
| Trophic Levels | are assigned to each organism. all members of the tropic level are the same number of energy transferring. |
| 1st Trophic level | producers which are autotrophs can produce their own food |
| 2nd Trophic level | animals that eat plants |
| 3rd Trophic level | animals that feed on plant eaters and other carnivores. Most animal feed on more than one trophic level 7 feed on several differen species at each trophic level making up the food chain, eventually becoming the food web |
| Energy Usage | 10% used, 90% released by work such as moving, breathing, etc. |
