Ecology 112
| Question | Answer |
|---|---|
| "oikos" | Greek for "the place where one lives." |
| "ology" | Greek for "the study of."` |
| Ecology | The study of the relationships of living things (biotic) to each other and to their environment. |
| Biotic Factors | Plants, animals, insects (micro-organisms), their environment, their remains and features (eg. nests) associated with their activities. |
| Abiotic Factors | The physical+chemical components of an ecosystem (sunlight, temperature, wind, water, humidity, moisture). |
| Ecosystem | A community of living things interacting with each other and their non-living environment. |
| Sustainability | The ability to meet present needs without compromising the ability of future generations to meet their needs. |
| Sustainable Ecosystem | An ecosystem that is maintained through natural processes. |
| Artificial Ecosystems | Must be maintained eg. golf course, fish tank, park. |
| Photosynthesis | Happens in green plants that contain chlorophyll convert light energy into chemical energy. |
| Cellular Respiration | Process whereby all living things use oxygen to break down glucose to release energy; occurs in the mitochondria of plant+animal cells. |
| Biosphere | The region on Earth where all life exists. |
| Biome | A large geographical area (eg. the tundra) with a characteristic plant and animal community produced by the climate. |
| Ecosystem | A community of living things with each other and their non-living environment. |
| Community | Is made up of different living things together. |
| Atmosphere | The layer of gases surrounding the year. |
| Lithosphere | Earth's solid outer layer. |
| Biosphere | The zone around Earth where life can exist. |
| Ecological Niche | the role of the species within its ecosystem; includes what it feeds on, what eats it ad how it behaves. |
| Herbivores | Plant eaters. |
| Carnivore | Animal eaters. |
| Omnivore | Plant and animal eaters. |
| Scanvengar | Feed on the remains of another organism. |
| Decomposers | Feed on waste products or bodies of dead organisms. |
| Food Chains | A sequence of organisms, each feeding on the one before showing how energy is transferred from one organism to the next. |
| Food Web | Represents the feeding relationship in a community. |
| Biodiversity | The variety of life in an ecosystem; the greater the biodiversity, the more sustainable the ecosystem. |
| Plants | Absorb water for photosynthesis; lose most of it through transpiration (plant sweating) and respiration (cellular). |
| Animals | Drink water and eat; containing foods; lose water through breathing, evaporation from skin, passing off waste. |
| Carbon | The basic building block of living things. (organic contain C, H also N, O; found in the atmosphere and dissolved in oceans as CO2 (inorganic matter). |
| Decomposition | CO2 from body wastes and decay of dead matter (by decomposers) is released back into the atmosphere back into the atmosphere. |
| Combustion | Burning of fossil fuels (coal, petroleum, natural gas) releases CO2, CO as well as C back into the atmosphere. |
| Nutrient | Any chemical that is essential to living things; nutrients are cycled through ecosystems and geological processes. |
| Nitrogen-Fixation | Taking Nitrogen gas and converting it into NO3. |
| Lightning | This energy causes Nitrogen gas to combine with Oxygen gas forming Nitrates; the NO3 dissolved in rainwater, enters the soil and is absorbed by plants. |
| Nitrogen-Fixing Bacteria | Bacteria in soil and in some legume plants (clover, peas, alfalfa) take Nitrogen gas out of the air and combine it with Oxygen gas to form Nitrates. |
| Decomposers | Break down the wastes and dead plant and animal material into simple chemicals. Soil bacteria converts these chemicals into Nitrates for plants. |
| Denitrification | Some soil bacteria called denitrifying bacteria , take Nitrates, turn them into Nitrates and other bacteria turn the Nitrates back into Nitrogen. |
| Population | Members of the same species living in the same habitat. |
| Population Growth | (births+immigration)-(deaths+emigration) |
| Carbon Dioxide | CO2 |
| Glucose | C6 H12 O6 |
| Oxygen | O2 |
| Water | H2O |
| Nitrate | NO3, NO2 |
| Nitrogen | N2 |
| Cellular Respiration Formula | C6 H12 O6 + 6 O2 - 6 CO2 + 6 H2O + E (O6 + C6 H12 O6 - CO2 + H20 + E) |
| Energy | E |
| Photosynthesis Formula | CO2 + H20 - O2 + C6 H12 O6 |
| Organic | matter that contains carbon and hydrogen atoms (and sometimes nitrogen and oxygen |
| Inorganic | matter that doesn't contain carbon and hydrogen eg. CO2, H2O |
