Cycles/Science
Test 1 on Cycles in Science
| Question | Answer |
|---|---|
| What are the FOUR elements most abundant in living organisms? | - Carbon - Oxygen - Nitrogen - Hydrogen |
| What is an EMISSION? | a pollutant released into the atmosphere |
| What is DENITRIFICATION? | releasing nitrogen from the soil back into a form that can be used by plants. |
| What is NITROGEN FIXATION? | the process of converting nitrogen in the air into a form that can be used by plants. |
| What is a LEGUME? | A plant with nitrogen fixing nodules on their roots |
| What is CELLULAR RESPIRATION? | Process by which an organism's body releases energy from carbon-based molecules. |
| What is PHOTOSYNTHESIS? | The process plants use to make sugar form sunlight water and carbon dioxide. |
| What are FOSSIL FUELS? | Fuels used in cars and factories that make pollution. |
| What is a COLLECTION? | Precipitation that gathers into a body of water. |
| What is RUNOFF? | Precipitation that flows over the surface of soil. |
| What is PHOTOCHEMICAL SMOG? | brown smog created when pollutants react with the air. |
| What is BIOCHEMICAL CYCLE? | cycling of chemical elements through the living and nonliving parts of an ecosystem. |
| What is a NODULE? | swelling on a plant root that contains nitrogen-fixing bacteria. |
| Can you draw a water cycle? | (Look at in note book) |
| Can you draw a carbon and oxygen cycle? | (Look at in notebook) |
| How should you show care with a microscope? | - Always hold the base and arm when moving microscope. - Always start with the smallest objective and move stage to the very bottom when adding a slide. - When using larger objectives, only use fine adjustments |
| What will affect an ecosystem? | Cutting down trees would result in too much carbon dioxide for producers to take care of, the ecosystem could lose nitrogen and important nutrients in any ecosystem. |
| Producers | plants and organisms that go through photosynthesis. |
