| Question | Answer |
|---|---|
| process in which producers make energy-rich nutrient molecules from chemicals | chemosynthesis |
| features of the environment that are alive or were once alive | biotic |
| model describing how carbon molecules move between the living and nonliving world | carbon cycle |
| process that takes place when a gas changes into a liquid | condensation |
| air surrounding the earth that is made up of nitrogen, oxygen, argon, carbon dioxide and traces of other gases | atmosphere |
| average weather conditions of an area over time, including wind, temperature, and precipitation | climate |
| model that shows the amount of energy available at each feeding level in an ecosystem | energy pyramid |
| process in which some types of bacteria can form the nitrogen compounds that plants need | nitrogen fixation |
| mixture of minerals and rock particles and the remains of dead organisms | soil |
| model describing how water moves from earth's surface to the atmosphere and back to the surface of the earth again through evaporation, condensation, and precipitation | water cycle |
| model describing how nitrogen moves from the atmosphere to the soil, to living organisms, and then back to the atmosphere | nitrogen cycle |
| nonliving, physical features of the environment, including air, water, sunlight, soil, temperature, adn climate | abiotic |
| model that show the complex feeding relationships among organisms in a community | food web |
| process that takes place when a liquid changes into a gas | evaporation |
