Chp 1 Natural Cycles
| Question | Answer |
|---|---|
| the science word for "living" | biotic |
| this is produced when air pollutants react with sunlight | photochemical smog |
| the process of chemical elements moving through the living and nonliving parts of an ecosystem | biogeochemical cycles |
| nitrogen combines with water vapor in the air making rain that is more acidic than normal rainwater | acid precipitation |
| we burn these (coal, natural gas, oil) for electricity, heat, or fuel, and in the process, they release carbon as carbon dioxide into the atmosphere | fossil fuels |
| a gas that animals and people give off and plants take in | carbon dioxide |
| the process where plants take in carbon dioxide, water, and sunlight and produce sugar for food and release oxygen into the atmosphere | photosynthesis |
| the process in animals and people where cells take oxygen and glucose and produce energy and release carbon dioxide | cellular respiration |
| organisms that are dependent on producers for oxygen | consumers |
| the way a carnivore gets the carbon it needs | by eating |
| the percentage of nitrogen gas in the atmosphere | 78 % |
| type of plant that hosts nitrogen-fixing bacteria on its roots | legume |
| swellings on roots of legumes where bacteria convert nitrogen into a usable form | nodules |
| the process that releases nitrogen from the soil back into the atmosphere {also performed by bacteria!} | denitrification |
| plants and animals need nitrogen to make this molecule | protein |
| precipitation that runs over the soil and is not absorbed into the soil | runoff |
| the process by which water falls from the atmosphere to Earth in the form of rain, snow, hail, or sleet | precipitation |
| the process that occurs when water changes from a liquid to a gas, caused by heat | evaporation |
| the process where water vapor turns back into a liquid in the atmosphere caused by cooling temperatures | condensation |
| the process where plants lose water to the atmosphere through their leaves | transpiration |
| the four most abundant elements in living things | hydrogen, oxygen, carbon, and nitrogen |
| examples of abiotic components of ecosystems | sand, air, water, sun |
| the organisms responsible for both processes of the nitrogen cycle | bacteria |
| a substance made of only one type of atom | element |
| the chemical pollutant that is responsible for the development of photochemical smog and acid precipitation | nitrogen |
