| Question | Answer |
| Biotic | living; refers to living things in the environment, such as humans, trees, fish, or bacteria |
| Abiotic | non-living; refers to non-living things in the environment, such as sunlight, water, soil, air, or minerals |
| Species | population of organisms capable of interbreeding and producing fertile offspring |
| Population | any group of individuals of the same species living in the same geographical area at the same time |
| Community | all of the organisms in all the interacting populations in a given area |
| Ecosystem | a community of populations, together with abiotic factors that surround and affect it |
| Biosphere | all of the areas on Earth (in the air, land, and water) that are inhabited by and that support life |
| Taxonomy | practice of classifying organisms based on common fundamental characteristics |
| Kingdom | the second highest taxonomic classification of all living things (below domain); the six kingdoms recognized in biology are Archaea, Bacteria, Protista, Fungi, Plantae, and Animalia |
| Domain | the highest level of classification of living things (above kingdom); three domains are Bacteria, Archaea, and Eukarya |
| Binomial Nomenclature | a system in which a two-word name (genus plus species) is used to identify an organism |
| Dichotomous Key | identification key that uses a series of paired comparisons to sort organisms into smaller and smaller groups |
| Climate | average weather conditions in a particular region over a period of time, usually 30 years or more |
| Biome | ecosystem or group of ecosystems in a specific region on Earth that has a particular combination of biotic and abiotic factors; for example, tundra, tropical rain-forest, hot desert |
| Habitat | place or area with a particular set of characteristics, both biotic and abiotic, in which an organism lives and is able to survive and reproduce because of particular physical, physiological, and behavioral adaptations |
| Range | geographical area in which a population or species is found |
| Ecological Niche | the role that members of a population play in a community, including the resources that members need and the way in which members interact with other members of the population and the community |
| Biodiversity | the variety of species in an area and their range of behavioral, ecological, physiological, and other adaptations |
| Limiting Factor | any biotic or abiotic condition that limits the number of individuals in a population |
| Sample | a portion of an entire population; samples are counted or estimated and the results are averaged and then applied, or extrapolated, to the entire area occupied by the population |
| Transect | a long, relatively narrow rectangular area marked out in a study area for the purpose of sampling a population |
| Quadrat | area of determined size that is marked out for the purpose of sampling a population; often used to sample plants and other organisms that tend to stay in one spot all their lives |
| Density | in population dynamics, the number of individuals per unit of area or volume in a population |
