APES - unit 2
| Question | Answer |
|---|---|
| Study of the interactions of living organisms with one another and with their nonliving environment of matter and energy | Ecology |
| Group of individual organisms of the same specie living within a particular area | Population |
| Populations of all species living and interacting in an area at a particular time | Community |
| Community of different species interacting with one another and with the chemical and physical factors making ups its nonliving environment | Ecosystem |
| The zone of earth where life is found | Biosphere |
| The whole mass of air surrounding the earth | Atmosphere |
| The earth's (1) liquid water oceans (2) frozen water (3) water vapor in atmospher | Hydrosphere |
| Terrestrial regions inhabited by certain types of life, esp. vegetation | Biome |
| Transitional zone in which one type of ecosystem merges with another type | Ecotone |
| Factors of or related to life | Biotic Factors |
| not alive, are nonliving factors that affect living organisms. | Abiotic Factors |
| range of chemical and physical conditions that must be maintained for populations of a species to stay alive and grow normally | Range of Tolerance |
| A single factor that limits the growth, abundance, or ditribution of the population of a species in an ecosystem | limiting factor |
| organism that uses solar energy or chemical energy to mfg the organic compounds it needs as nutrients | Producer/ Autotroph |
| organism that cannot make the organic nutrients it needs | Consumer/ Heterotroph |
| consumer organism that feed on parts of dead organisms | Detritivore |
| animals that feed on animal-eating animals | Tertiary consumers |
| A process in which energy from the sun is used to produce oxygen and carbohydrates (in cells of green plants) | Photosysthesis |
| process in which nutrient organic molecules such as glucose combines with O2 to produce CO2 and water and energy | Aerobic respiration |
| form of cellular respiration in which some decomposers get energy through the breakdown of glucose in the absence of oxygen | Anaerobic respiration |
| Variety of different species, varied genes within a species | Biodiversity |
| Role of a species in an ecosystem | Niche |
| the full potential range of the physical, chemical, and biological factors a species can use if there is no competition from other species | Fundamental Niche |
| Parts of the fundamental niche of a species that are actually used by that species | Realized Niche |
| Species with a broad ecological niche | Generalist species |
| Species with a narrow ecological niche | Specialist species |
| A genetically controlled characteristic that helps an organism survive and reproduce | Adaptation |
| Change of the genetic makeup of a population in successive generations | Evolution |
| process by which a particular beneficial gene is reproduced in succeeding generations more than other genes | Natural Selection |
| resemblance between species belonging to different taxonomic groups as result of adaptation | Convergent Evolution |
| "In all physical and chemical changes energy is neither created nor destroyed, but may be converted from one form to another" | First law of thermodynamics |
| "When energy is converted from one form to another, some of the useful energy is always degraded to lower quality, more dispersed, less useful energy" | Second law of thermodynamics |
| series of organisms in which each eats or decomposes the preceding one | Food chain |
| network of many interconnected food chains and feeding relationships | Food Web |
| All organisms that are the same number of energy transfers away from the original source of energy | Trophic level |
| organic matter produced by plants and other producers | Biomass |
| an illustration of the energy loss for a food chain | Trophic pyramids |
| the amount of biomass that is available for use as food by other organisms in an ecosystem | NPP (net primary productivity) |
| The RATE in which plants or other producers use photosynthesis to make more plant material | GPP (Gross primary productivity) |
| species that play roles affecting many other organisms in an ecosystem | Keystone Species |
| species that serve as early warnings that a community or ecosystem is being degraded | Indicator species |
| graph showing the # of survivors in different age groups for a specific species | Survivorship Curves |
| the selection of combinations of traits in an organism that trade off between quantity and quality of offspring. | R-K-selected |
| organisms that have many offspring that don't need as much care (in environments that can change rapidly) | R-Selected |
| organisms that have few offspring, usually larger, that need a lot of care (in environments that are stable) | K-selected |
