| Question | Answer |
|---|---|
| biology | the scientific study of life |
| biosphere | all the environments on earth that support life |
| ecosystem | all living organisms and non living components in an area |
| community | all organisms inhabiting an ecosystem |
| population | species in a community |
| organism | individual living thing |
| organ system | several organs working together for a single purpose |
| organ | group of tissues |
| tissues | a group of similar cells that perform a specific function and make up an organ |
| cell | a unit of living matter separated from its environment by a membrane |
| organelle | the small structure inside a cell that performs a special function |
| molecule | cluster of atoms held together by a chemical bond |
| atom | smallest particle of ordinary matter |
| producers | provide food for a typical organism |
| consumers | organisms in an ecosystem that eat plants or other animals |
| decomposers | members of the ecosystem who are recyclers, they change complex matter into simple nutrients |
| emergent properties | properties that arise from the structure level of a cell "whole is greater that the sum of its parts" |
| prokaryotic cell | cell that lacks a nucleus and other internal compartments |
| eukaryotic cell | type of cell that has internal membranes that divide up into compartments like a nucleus |
| taxonomy | branch of biology that names and classifies species |
| domains | above kingdom level, three domains |
| theories | ideas that have the ability to explain and synthesize |
| natural selection | a mechanism by which living things change over time |
| evolutionary adaptation | accumulation of favorable variations in populations over time |
| ecology | study of the interaction of organisms and their environments |
| abiotic component | non-living factors in an environment |
| biotic component | made up of all organisms making up communities in an ecosystem |
| biosphere | global ecosystem |
| habitats | specific environments in which organisms are found |
| tropics | region between latitudes 23.5 degrees north and 23.5 degrees south |
| doldrums | an area of calm or very light winds |
| trade winds | cooling winds which dominate the tropics and are produced as dry air that descends and spreads back towards the equator |
| temperate zone | latitudes between tropics and Arctic/Antarctic north and south respectively |
| ocean currents | river flow like patterns in the ocean |
| biomes | the world's largest ecosystems |
| intertidal zone | area of shore where land meets the ocean |
| pelagic zone | open ocean waters |
| phytoplankton | formed from microscopic algae and cyanobacteria |
| zooplankton | small drifting animals that eat phytoplankton |
| benthic zone | sea floor |
| photic zone | part of the ocean that light reaches |
| aphotic zone | part of the ocean that light does not reach |
| continental shelves | part of the continent that is under water |
| coral reefs | warm, tropical waters above continental shelves, built up slowly by successful coral |
| estuary | where fresh water meets with ocean water |
| wetland | transitional between terrestrial and aquatic ecosystems |
| tropical forests | occur in equitorial areas, warm temperatures, poor soil, 11-12 hour days |
| savannas | grasses and scattered trees, lots of fire, 30-50 cm of rain a year |
| deserts | dry, almost no rainfall, mostly hot with major temperature fluctuations |
| desertification | conversion of semi-arid regions to desert |
| chapparal | dense spiny shrubs with evergreen leaves, in coastal areas, mild rainy winters and wet dry summers |
| temperate grasslands | like savannas but treeless, usually cold winters |
| temperate broadleaf forests | mid-latitude regions, evenly distributed precipitation, cold in winter, hot in summer |
| coniferous forests | cool high elevations, long cold winters and short wet summers |
| tundra | northernmost area of growth, very cold, little light |
| permafrost | continuously frozen subsoil |
