| Question | Answer |
| Sustainability | A balance between Earth's resources, human needs, and the needs of other species. |
| Ecological (carbon) footprint | The amount of carbon emitted and its environmental impact. |
| Greenhouse effect | the process through which heat is trapped near Earth's surface by substances called "greenhouse gasses". |
| invasive species | an introduced species to an environment that becomes overpopulated and harms its new environment. |
| Explain the influence humans have on the three biogeochemical cycles we discussed in concept 2. | Water cycle- Deforestation affects the transpiration stage. Carbon cycle- Combustion pollutes the air, earth, and water. Nitrogen cycle- Over fertilizing the soil creates a nitrogen imbalance. |
| List examples of renewable and nonrenewable sources. | Renewable: oxygen, wood, water, sunlight, and wind. Nonrenewable: fossil fuels, metals and plastics. |
| Summarize the goals of each type of technology, and include one positive and one negative outcome for each. | Agricultural Alternative Industrial |
| Agricultural | Agricultural: Increase food productivity Pro: Contour farming Con: Pollution |
| Alternative | Alternative: Providing clean energy to power society Pro: Decreases burning fossil fuels. Con: Expensive |
| Industrial | Industrial: Increase manufacturing, transportation, and communication efficiency Pro: Improves communication Con: Creates harmful CFC's |
| Replace the italicized word to make the statement true: GENETIC DIVERSITY, refers to the variety of ecosystems that are present in the biosphere. | ECOSYSTEM DIVERSITY |

| Describe 2 key contributors to global warming | Fossil fuels and CFC's |
| List three ways humans threaten biodiversity | 1) Destroying habitats 2) Pollution 3) Introducing invasive species |
| Differentiate between direct & indirect economic value of biodiversity | Direct = benefit derived from products provided by biodiversity EX: food, wood, medicines Indirect = benefit that's consistent w/ services derived from biodiversity & of great value 2 society as a whole, not individuals/businesses EX: pollination by bees |
