|---|---|
| What are some important concepts in Ecology? | Reservoir, Biotic, Abiotic, Species, Population, Community, Niche, Habitat, Biomes, Atmosphere, Lithosphere, Hydrosphere, Biosphere. |
| What are the names of biomes found in Canada? | Deciduous forests, boreal forests (AKA taiga), artic tundra, grasslands, temperature coniferous forests. |
| What is the process of photo synthesis? | when plants take sunlight to make energy. this usually occurs in green plants. |
| What is the word equation for photosynthesis? | carbon dioxide + oxygen ---> [sunlight] water + usable energy + glucose (glucose) |
| what is the process of cellular respiration? | they take food (glucose) and make it into cellular energy. |
| What is the word equation for cellular respiration? | water + glucose (sugar)---> [cells] carbon dioxide + oxygen |
| define extinct | a species that is not found anywhere. (blue walleye passenger pigeon) |
| define endangered | a species that is close to extinction in all parts of Canada or a significantly large area. (beluga whale) |
| define extirpated | any species that no longer exists in one area but can be found in others. (grizzly bear) |
| define threatened | any species that is likely to become endangered if factors that make it vulnerable are not reversed. (wood bison) |
| define special concern | a species with characteristics that make it sensitive to human activities or natural events. (grey fox) |
| what is an ecological footprint? | an estimate of how much land is water is needed to support your lifestyle. |
| whats an environmental steward? | taking care of our natural resources to ensure they are used in sustainable ways for current and future generations. |
| how does energy move in ecosystems? explain the 10% rule. | 10% of the energy in food is used to make body tissues such as bones, muscles, and fat. 10% of the energy that the animal eats is available to pass on to the animal in which eats it. 90% is lost in transfers. |
| explain the process of the 10% rule | theres 1 million joules of sunlight, the primany producers take 10% of that energy, the primary consumers eat the primary producers & gain 10% of their energy, then the secondary consumers gain 10% of theit energy, then the tertiary consumers get 10% 10j |
