|---|---|
| producer/autotroph | can make their own food by photosynthesis (examples are plants) |
| consumer | has to eat other things to get energy (examples are animals |
| herbivore | eats only plants |
| carnivore | eats only animals |
| decomposer | breaks down waste and decaying material (example is mushrooms) |
| scavenger | feeds on waste or decaying material |
| precipitation | rain, snow, hail, sleet |
| evaporation | liquid water turns to water vapor (gas) (example is lake/ocean water going into the air) |
| condensation | water vapor (gas) turns to liquid water (example is clouds) |
| oxygen | what animals breathe in and what plants make/put out in photosynthesis |
| carbon dioxide | what animals breathe out and what plants take in |
| renewable resource | resource that's always available or naturally replaced in a relatively short time (sunlight, wind, water, trees, animals) |
| nonrenewable resource | natural resource that is not replaced in a useful time frame (oil, coal, petroleum) |
| habitat | specific environment that provides the things an organism needs to live, grow, and reproduce |
| species | group of organisms that physically similar and can mate and produce fertile offspring |
| population | all the members of one species in a particular area (group of wolves living together, group of apple trees growing together, etc) |
| community | all the different populations that live together in an area (populations of plants and animals living together) |
| ecosystem | plants and animals living together along with their nonliving surroundings |
| biotic factors | the living parts of a habitat (plants and animals) |
| abiotic factors | the nonliving parts of a habitat (sun, water, temperature, oxygen, rocks, etc) |
| natural selection | better adapted individuals survive, reproduce, and eventually become the common species |
| adaptation | behavior or physical characteristic that helps an organism survive |
| niche | role an organism has in its environment or how it makes its living (what it eats, what eats it, etc) |
| biome | group of land ecosystems with similar climates and organisms |
| ecology | study of how living things interact with each other and their environment |
| biodiversity | the number of different species in an area |
| tropical rain forest | warm and humid all year, LOTS of rain, trees, vines, flowers, insects, reptiles, birds, monkeys, gorillas, frogs, etc. |
| grassland | warm, 25-75 cm of rain per year, grasses, shrubs, elephants, antelopes, zebras, giraffes, cheetahs |
| desert | hot during the day, cold at night, less than 25 cm of rain per year, cactus, quail, lizards, snakes, meerkats |
| tundra | very cold and dry, less than 25 cm of rain per year, moss, grasses, shrubs, insects, birds, caribou, foxes, wolves, hares |
| boreal forest | cold winters, warm summers, 20-75 cm of rain per year, fir and spruce trees, moose, wolves, bears, owls, lynx |
| deciduous forest | temperatures vary greatly throughout the year, at least 50 cm of rain per year, oak trees, maple trees, birds, chipmunks, deer, black bears, red fox |
| temperate rain forest | moderate temperatures, 300 cm or more of rain per year, cedar tree, redwoods, deer, bears, woodpeckers |
