extreme temperatures with minimal water. Plants and animals are biologically limited in productivity and diversity.soils are drainage-loose instead compact (plants):wildflowers, cactus and succulents, trees, shrubs, grasses, creosote shrubs, riverside cottonwoods, willows/ (animals,mammals): bears, bobcats, coyotes, kit foxes, mule deer, raccoons, rabbits, gophers, squirrels,bird,fish,reptiles,amphibians,insects,spiders, area where the ocean meets the land, especially that area that is affected by the changing tides(low-high). (animals): seastars, anemones, snails,bird,fish,crabs/ (plants): algae-green,brown,red, surf grasses, eel grasses/ (temp):air can range from below freezing to extremely hot/ spray zone-limpets, acorn barnacles/high tide-crab/ middle tide-green algae, sea lettuce,shrimp/ low tide-sea cucumber, sea palms, limpets high nutrient environment, high planktonic growth, extensive aquatic plant beds, much sediment accumulation, low dissolved oxygen on the bottom. have "tea- colored" or cloudy water, warmer water temperatures,/ habitation by warm water fish species- big and little sunfish, varieties of bass, yellow perch, black and white crappie, bluegill, channel catfish, carp ,pickerel. dominant vegetation in temperate grasslands. rainfall occurs in late spring and early summer. Temp range 40 -100 in the summer. Vegetation found in here varies according to rainfall./ located in North America, the former Soviet Union, Hungary, South Africa, Uruguay ,Argentina. / seasonal droughts and occasional fires- plant roots stay undamaged./ Prairie vegetation - purple needlegrass, galleta, buffalo grass, blazing stars,asters, goldenrods, sunflowers, wild indigos,clovers. coldest of all Earth's biomes. has numerous living and nonliving elements. divides into arctic and alpine tundra. low temp and high winds/ ABIOTIC: low temp and high winds / BIOTIC(plants): low shrubs, sedges, grasses, reindeer moss, variety of lichens/ (animals as consumers):caribou, reindeer, arctic hare, ptarmigan, lemmings, musk oxen /(animals as predators):arctic fox, snowy owls, polar bears,wolves/ biotic and abiotic factors work together to shape the tundra and keep the ecosystem functioning.
