| Question | Answer |
|---|---|
| fundamental niche | the entire range of conditions an organism can tolerate |
| realized niche: | : the part of its fundamental niche that a species actually occupies |
| population | group of individuals that belong to the same species, live in the same area, and breed with others in the group |
| species | group of organisms that look alike and are capable of producing fertile offspring in nature |
| ecosystem: | ecological system encompassing a community and all the physical aspects of its habitat |
| organism | a living thing that has (or can develop) the ability to act or function independently |
| community | the many different species that live together in a habitat |
| competition: | ecological interaction between two or more species that use the same scarce resources such as food, light, and water |
| symbiosis | ecological interaction in which two or more species live together in a close, long-term association |
| commensalism | ecological interaction in which one species benefits and the other species is neither harmed nor helped |
| parasitism: | type of predation in which the predator feeds on but usually does not kill a larger organism |
| mutualism: | symbiotic association in which both partners benefit |
| biodiversity: | the variety of species living within an ecosystem |
| species richness: | umber of different species |
| species diversity: | variety of species |
| carrying capacity | population size that an environment can sustain |
| population density: | in a population, the number of individuals in a given area |
| exponential growth: | growth at a constant rate of increase per unit of time |
| genetic diversity: | variation among and within species that is attributable to differences in hereditary material |
| biome: | major type of terrestrial ecological community, such as a grassland and desert |
| air pollution | sox and nox sulfur and nitrogen oxides |
| eutrophication | over-enrichment of a water body with nutrients, resulting in excessive growth of organisms and depletion of oxygen concentration |
| renewable resources: | a resource that can potentially last as long as the sun is around because it can be renewed fairly rapidly through natural processes |
| emigration: | the movement of organisms out of an area |
| immigration | the movement of organisms into an area |
| mortality: | death rate |
| natality: | birth rate |
| chlorofluorocarbon (CFC): | any of a group of compounds that contain carbon, chlorine, and fluorine, often used as coolants, propellants, or foaming agents |
| greenhouse effect: | atmospheric warming resulting from heat trapped in gases such as carbon dioxide |
| global warming: | a gradual warming of the Earth's atmosphere reportedly caused by the burning of fossil fuels and industrial pollutants |
| acid precipitation: | precipitation with below-normal pH, often the result of industrial pollution and automobile exhaust |
| global population: | the total number of humans alive at a given time |
| abiotic factors: | physical aspects of a habitat |
