| Habitat fragmentation | when a habitat is divided into smaller pieces by roads or buildings |
| Plants | eukaryotes, multi-celled, producers |
| Endangered | when a species is in danger of becoming extinct |
| Fungi | eukaryotes, multi-celled, decomposers |
| Threatened | when a species is in danger of becoming endangered |
| Protists | eukaryotes, single or multi-celled, consumers |
| Extinct | the disappearance of all members of a species from earth |
| Bacteria | once belonged to the kingdom Monera |
| Keystone species | a species that influences the survival of many other species in an ecosystem |
| Archaebacteria | simple, single-celled, prokaryotes |
| Captive breeding | the mating of animals in zoos or wildlife preserves |
| Eubacteria | single-celled, prokaryotes |
| Invasive exotic species | a species that is not native to an area and takes over the ecosystem |
| Factors affecting biodiversity | area, climate, niche diversity |
| Biodiversity | the number of different species in an area |
| Fujita Scale | Rating system for tornadoes |
| Desert | Hot and dry,Cactus, short shrubs, Kangaroo rats, snakes |
| Grassland (savanna) | Hot and not as dry as desert, Grass, shrubs, Antelope, elephants |
| Tundra | Cold and dry-snow, Not many—low shrubs, sedges, reindeer moss, Caribou, arctic hare, polar bears |
| Taiga/Boreal forest | Cold and average precipitation, Coniferous trees (pine trees), Moose, bears, mountain lion |
| Tropical Rainforest | Hot and lots of precipitation, bamboo, ferns, mosses, MANY animals—insects, arachnids, snakes, monkeys |
| Temperate Rainforest | Average temperature and lots of precipitation, Redwood trees, Northern spotted owl, pacific salmon |
| Temperate Deciduous Forest | WE LIVE HERE, Average temperature and average precipitation, Oak trees, maple trees, Squirrels, deer |
| Saffir-Simpson Scale | Rating system for hurricanes |
| Troposphere | Closest to earth, Weather happens, Airplanes fly |
| Stratosphere | Ozone layer, Jet stream |
| Mesosphere | Coldest layer, meteors burn up |
| Thermosphere | Furthest from earth, Northern lights, satellites |
| Maritime polar air mass | Forms over water/cold areas, Brings wet and cold weather |
| Maritime tropical air mass | Forms over water/warm areas, Brings wet and warm weather |
| Continental polar air mass | Forms over land/cold areas, Brings dry and cold weather |
| Continental tropical air mass | Forms over land/warm areas, Brings dry and warm weather |
| Thermometer | Used to measure temperature |
| Barometer | Used to measure air pressure |
| Hygrometer | Used to measure relative humidity |
| Anemometer | Used to measure wind speed |
| Rain gauge | Used to measure amount of rainfall |
| Cumulus | Low level, puffy, Fair weather |
| Cumulonimbus | Throughout all altitudes, Thunderstorm cloud |
| Stratus | Low altitudes, Flat, overcast, rain, drizzle |
| Cirrus | High altitudes, Wispy, ice crystals, pleasant weather |
| Front | A boundary between air masses |
| Warm front | Rain followed by warmer weather |
| Cold front | Storms followed by cool weather |
| Condensation | The process in which water vapor (a gas) in the air turns into liquid water |
| How clouds form | water vapor rises, cools, and condenses |
| Precipitation | The process in which water (in the form of rain, snow, sleet, or hail) falls from clouds in the sky |
| where is tornado alley | central united states |
| Low air pressure | Indicates a rainy day |
| High air pressure | Indicates a sunny day |
| Evaporation | The process in which liquid water becomes water vapor (a gas), liquid warms up |
| the sun | primary cause of all weather on earth |
| Conduction | Heat transfer by direct touching |
| Convection | Heat transfer by hot air/water rising and cool air/water sinking |
| Radiation | Heat transfer through space |
| Coriolis Effect | The curving of winds to the right or left caused by the rotation of earth |
| Relative Humidity | The % of moisture the air holds relative to the amount it could hold |
| Isobars | Lines on a map connecting areas of equal air pressure |
| Isotherms | Lines on a map connecting areas of equal temperature |
| Land breeze | A breeze blowing from the land to the sea |
| Sea breeze | A breeze blowing from the sea to the land |
| correct order of classification | kingdom, phylum, class, order, family, genus, species |
| Omnivore | An animal that eats BOTH plants AND animals, Bear, pig, crow, human |
| Herbivore | An animal that eats ONLY plants, Deer, cow, sheep |
| Carnivore | An animal that eats ONLY animals, Wolf, lion, polar bear |
| Commensalism | A relationship among organisms where one benefits and the other is neither helped NOR harmed, Remora fish attaching to shark |
| Parasitism | A relationship among organisms where one benefits and the other is harmed Flea, tick, tapeworm, HOST-dog, human, PARASITE-flea, tick |
| Fragmentation | A type of asexual reproduction where the parent breaks into different fragments, which eventually form new individuals(flatworms) |
| Correct way to write a scientific name | In italics, genus capitalized, species lowercase |
| Mutualism | A relationship among organisms where BOTH benefit, Ex. Ants and aphids |
| Radial Symmetry | When an organism has many lines of symmetry, usually on round objects and those found in the sea, Starfish, sponge |
| prokaryotes | NO nucleus |
| adaptation | A structure, function, behavior, or any characteristic that helps an organism survive in its environment and reproduce |
| Eukaryotes | DO have a nucleus |
| Structural adaptation | Hawk’s sharp talons, frog’s sticky tongue |
| Functional adaptation | Abalone’s ability to suction onto a rock |
| Behavioral adaptation | Bear’s hibernation pattern |
| order of living things | cell, tissue, organ, organ system |
| thorax | where legs and wings are attached on an insect |
| binomial nomenclature | the two-part naming system for organisms |
| number of body parts of an insect | three |
| dichotomous key (taxonomic key) | SERIES OF PAIRED STATEMENTS, special guide developed by taxonomists to help identify unknown organisms by answering a series of yes or no questions (remember the alien activity) |
| what are the body parts of an insect | head, thorax, abdomen |
| Bilateral Symmetry | When an organism has only one line of symmetry |
