| Question | Answer |
|---|---|
| population | a group of individuals of the same species living in the same area |
| community | a group of populations occupying the same area and sharing resources |
| atmosphere | the envelope of gases surrounding the Earth |
| lithosphere | the crust and upper mantle of the Earth |
| hydrosphere | all the water on the Earth's surface including clouds |
| biosphere | all the living things on the Earth |
| trophic level | a level in an ecosystem containing all organisms that share the same function in a food chain |
| primary producer | those organisms in a food chain that produce organic molecules from inorganic elements and energy (usually from the sun) |
| autotroph | an organism that produces its own food, a primary producer |
| heterotroph | an organism that must eat other or organisms for energy |
| primary consumer | organisms that eat primary producers, herbivores |
| omnivore | an organism that eats plants and animals |
| carnivore | an organism that eats other animals, a secondary consumer |
| secondary consumer | organisms that eat primary consumers |
| decomposer | bacteria, fungi and invertebrates that ingest and break down dead organisms |
| scavenger | an animal that feeds on carrion and dead plant material |
| food web | a system of interdependent food chains |
| food chain | A series of organisms each dependent on the next as a source of food |
| symbiosis | A close, prolonged association between two or more different organisms of different species |
| parasitism | symbiotic relationship in which one organism benefits and the other is harmed |
| mutualism | symbiotic relationship in which both organisms benefit |
| commensalism | symbiotic relationship in which one organism benefits and the other is neither harmed nor benefited |
| predation | when one organism of the same or different species eats another organism |
| competition | when two or more organisms use the same resources, where one organism's fitness is increased while the other's fitness is decreased |
| percolation | the slow passage of water through soil into the lithosphere |
| evaporation | liquid water heating up, changing state to vapor |
| transpiration | the evaporation of liquid water from plants |
| precipitation | rain, snow, hail or sleet that falls to the ground |
| condensation | water molecules collecting as droplets |
| ground water | water in the lithosphere |
| run off | water that moves over the surface after precipitation |
| surface water | water on the surface of the Earth including water vapor in the atmosphere |
| respiration | the metabolic processes by which living cells produce energy through the oxidation of organic substances, releases water/heat/CO2 |
| photosynthesis | The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and energy from the sun |
| nitrogen fixation | chemical processes by which atmospheric nitrogen is turned into organic compounds, by bacteria in soil and water |
| denitrification | chemical processes by which nitrogen containing compounds are turned back into nitrogen gas |
| fossil fuels | organic compounds formed in the geological past from the remains of living organisms. |
