1 A group of land ecosystems with similar climates and organisms. BiomesA group of land ecosystems with similar climates and organisms.
2 Types of Biomes Desert Grasslands Temperate Forests/Deciduous Forest Tropical ForestsTaiga/Coniferous Forest/Boreal ForestAquatic: Oceanic and Fresh WaterTundra
3 Desert Biome Middle latitudes Very little precipitation: less that 25 cm/yearCan be hot or coldVegetation: cacti, desert plantsLizards, snakes, kangaroo rat, owls, foxes, javelinas, coyotes
4 Grasslands Found in the middle latitudes Moderate rainfall: cm per yearGrasses but few forestsPeriodic wildfiresGrazing animals: bison, horses, gazelles, zebras, wolves, tigers and lions.
5 Temperate/Deciduous Forests Forest biomeShort winters (2 months)75 to 150 cm of rainfall per yearBroad leaf treesMost trees loose leaves and go dormant in winterVariety of animals: squirrels, deer, raccoons, wolves, foxes, bobcats, many insects
6 Tropical/Rain Forests Near the equatorWarm to hot temperaturesAbundant rainfall: 250 to 400 cm per yearMany plants, animals and insectsMonkeys, birds, insects, snakes
7 Boreal/Coniferous Forests (Taiga) Very coldConiferous trees (Pine trees)More rain than Tundra: cm per yearDeer, elk, beavers, bears, wolves, owls
8 Aquatic Freshwater Biomes: Marine Biomes: Rivers & streams Lakes & pondsEstuaries (mixture of fresh and saltwater)Marine Biomes:CoastalOpen oceanDeep ocean
9 Tundra Very cold and dry -50 degrees F less than 25 cm of rain per yearNorthern-most part of the globe: ArcticOwls, bears, small rodents, white fox, caribou, oxen
