| Community | Interacting populations of all interdependent plant and animal species found in a particular habitat. |
| Conservation | The wise use and management of out renewable natural resources. |
| Consumer | An organism which must eat other organisms for food (e.g: Animals). |
| Decomposer | An organism which obtains every by breaking down dead organic matter. (e.g: Bacteria, Fungi) |
| Ecological Niche | The "place" occupied by a species in its habitat, including the particular set of circumstances (Chemical, Physical, Biological) that enable it to survive. |
| Ecosystem | All the interacting parts of the physical and biological worlds. |
| Food Chain | The passage of energy through populations in a community (i.e. energy and nutrients pass from plants to animals, then to other animals). |
| Food Web | An abstract representation of the various paths of energy flow through populations in a community |
| Habitat | A natural home of a plant of animal. |
| Population | A group of individuals of one species found within a particular area. |
| Producer | A organism that produces its own food (e.g.: Plants) |
| Renewable Natural Resources | Naturally occurring assets such as vegetation, wildlife, soil, water, and air. |
| Species-at-Risk | A species identifies by Committee on the Status of Endangered Wildlife in Canada and is designated as a species of special concern, threatened, endangered of extirpated. |
| Stewardship | Management of the heritage of out natural spaces, species, and culture in such a way that it can be passed on to future Canadians intact. |
| Sustainable | Describes practices that allow for controlled consumption so that a renewable natural resource remains at the same level. |
| Watershed | The region or area bounded peripherally by a high-ground divide and draining ultimately to a particular watercourse of body of water; regardless of where you are,you are in a watershed. |
| Amphibian | A class of vertebrates able to live on land and in water (e.g. frog) |
| Biome | A natural region with characteristic plant and animal communities. |
| Biosphere | Regions of the earth's crust and atmosphere occupied by living matter. |
| Bird | Feathered vertebrate with two wings and two feet, egg laying and usually able to fly. |
| Carnivore | An animal that eats other animals for food; a meat eater (e.g. Wolf) |
| Fish | Vertebrate cold-blooded animal with gills and fins living wholly in water. |
| Herbivore | An animal that eats plants for food (e.g. Deer) |
| Insect | Small invertebrate animals with 6 legs, two or four winds and body in 3 segments. |
| Kingdom | Division of group of species in the natural world. |
| Mammals | Class of warm-blooded vertebrates characterized by secretion of milk to feed young. |
| Omnivore | An animal that eats both plants and animals for food |
| Predator | An animal that hunts other animals for food. |
| Prey | An animal hunted by other animals |
| Reptile | Class of cold-blooded vertebrates including snakes, lizards. crocodiles, turtles, and tortoises. |
| Scavenger | An animal that eats dead organisms (e.g.: turkey vulture) |
| Species | Class of living things (plants or animals) having some common characteristics. |
| Extinction | A species that has died out and no longer exists on earth. |
| Extirpated | A species that no longer exists in certain areas |
| Endangered | A species that will be extirpated of extinct if there is no intervention. |
| Threatened | A species likely to become endangered if factors harming it are not reversed |
| Special Concerned | A species that may be threatened or endangered due to multiple factors |
| Non-Native species | A species which had traveled from it's original ecosystem into a new ecosystem, generally transported by humans and often causes problems in the new environment. |
| Pests | Organism(s) that are problematic to humans especially in terms of crops |
| Resistance | genetic Propensity of pests to survive pesticides etc. due to the higher portion that survived and reproduce and pass on resistant genes. |
| Atmosphere | Layer of gases surrounding the earth, mostly nitrogen and oxygen |
| Lithosphere | Earth's rocky solid outer layer |
| Hydrosphere | All of earth's water in (solid, liquid and gas forms) |
| Biosphere | Locations where life can exist in the aforementioned spheres |
| Diversity | A wide variety of species (Flora/ Fauna) |
| Photosynthesis | The chemical process in which green plants convert sunlight energy into chemical energy. ( "Photo" means light and "synthesis" means to make). |
