| Question | Answer |
|---|---|
| abiotic factors | any nonliving factor in an organism's environment, such as soil, water temperature, and light availability |
| autotrophs | organism that captures energy from sunlight or inorganic substances to produce its own food; provides the foundation of the food supply for other organisms; also called a producer |
| biogeochemical cycles | exchange of matter through the biosphere involving living organisms, chemical processes, and geological processes |
| biological community | all the interacting populations of different species that live in the same geographic location at the same time |
| biomass | total mass of living matter at each trophic level |
| biome | large group of ecosystems that share the same climate and have similar types of communities |
| biosphere | relatively thin layer of Earth and its atmosphere that supports life |
| biotic factor | any living factor in an organism's environment |
| carnivore | heterotroph that preys on other heterotrophs |
| commensalism | symbiotic relationship in which one organism benefits and the other organism is neither helped nor harmed |
| denitrification | process in which fixed nitrogen compounds are converted back into nitrogen gas and returned to the atmosphere |
| detrivore | heterotroph that decomposes organic material and returns the nutrients to soil, air, and water, making the nutrients available to other organisms |
| ecology | scientific study of all the interrelationships between organisms and their environment |
| ecosystem | biological community and all the nonliving factors that affect it |
| food chain | simplified model that shows a single path for energy flow through an ecosystem |
| food web | model that shows many interconnected food chains and pathways in which energy and matter flow through an ecosystem |
| habitat | physical area in which an organism lives |
| herbivore | heterotroph that eats only plants |
| heterotroph | organism that cannot make its own food and gets its nutrients and energy requirements by feeding on other organisms; also called a consumer |
| matter | anything that takes up space and has mass |
| mutualism | symbiotic relationship in which both organisms benfit |
| niche | role, or position, of an organism in its environment |
| nitrogen fixation | process by which nitrogen gas is captured and converted into a form plants can use |
| nutrient | chemical substance that living organisms obtain from the environment to carry out life processes and sustain life |
| omnivore | heterotroph that consumes both plants and animals |
| parasitism | symbiotic relationship in which one organism benefits at the expense of another organism |
| population | group of organisms of the same species that occupy the same geographic place at the same time |
| predation | act of one organism feeding on another organism |
| symbiosis | close mutualistic, parasitic, or commensal association between two or more species that live together |
