| Ecosystem | All the living and nonliving things in an area that interact |
| Habitat | The environment where organisms lives |
| Organisms | One individual plant , animal or bacteria. |
| Population | All of the one type of organisms in one area. |
| Community | All the population in one area. |
| Biosphere | The biosphere is made up of all the living things on Earth and it includes fish, birds, plants, and even people |
| Producer | An organism, as a plant, that is able to produce its own food from inorganic substances. |
| Consumer | An organisms,usually an animal, that feeds on plants or other animals |
| Decomposer | An organisms, usually a bacterium or fungus,that breaks down the cells of dead plants and animals into simpler substances. |
| Herbivore | Animals that get their energy by only eating producers or plants |
| Carnivore | Animals that their energy by only eating other consumers |
| Omnivore | Animals that get their energy by only eating both producers (plants) and consumers (animals) |
| Scavenger | A consumer that eats dead animals . |
| Predator | Any organisms that exists by preying on other organisms. |
| prey | An animal hunted or seized for food ,especially a carnivorous animal |

| Food Chain | describes the order in which organisms, or living things, depend on each other for food. |
| Primary consumer | Primary consumers are organisms that eat ONLY producers and are all herbivores |
| Secondary consumer | Secondary consumers are those that consume the primary consumers (herbivores). |
| Tertiary consumer | Tertiary consumers are animals that consume other animals to obtain nutrition from them. |
| Trophic levels | The position an organism fills in a food chain is called a trophic level. |
| Autotroph | Autotrophs are living things that make their own food for energy from non-living substances in their environment. |
| Heterotroph | organisms that can't make their own food and so must get energy by eating plants and animals to survive. |
