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.

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)
