Biomes Where the plants and the animals live Biomes Large regions with plants and animals that are well adapted to the soil and climate of the region Biomes ➢Ice ➢Tundra ➢Taiga/Boreal/Coniferous Forests ➢Temperate Deciduous Forests ➢Chaparral ➢Grasslands ➢Savanna ➢Deserts ➢Tropical Rain Forests ➢Fresh Water ➢Wetlands ➢Ocean Ice ▪Below freezing all year round ▪No plants, but some algae live in the ice ▪Few animals live on the ice including polar bears, penguins, seals ▪Some live in the waters near and under the ice including fish and whales ▪Examples: Polar Caps, Greenland, high mountains such as the Andes, Himalayas ▪A cold and treeless area ▪Very little precipitation, Tundra similar to a desert (15 to 25 cm annually) ▪Alpine tundra is above the tree line in mountains throughout the world ▪Frozen layer called permafrost just below the surface never thaws ▪Lichens, moss, and short, hardy, shallow-rooted plants ▪Mosquitoes, flies, other insects ▪Caribou, reindeer, mountain goats and sheep, snowshoe rabbits Coniferous Forests ▪Average of 25 to 100 cm annual precipitation (mostly snow) ▪Cooler temperatures reduce evaporation ▪Short summers ▪Long, cold, dry winters ▪Lower plant and animal diversity due to harsh winters ▪Pine, spruce, douglas fir ▪Elk, moose ▪Squirrels, snowshoe hare ▪Lynx, bobcat Taiga/Boreal Forests Deciduous Forests ▪Receive between 70 and 150 cm annual precipitation ▪Four distinct seasons ▪Leaves fall off in the fall ▪Trees include oak, elm, maple, willow ▪Animals include squirrels, deer, foxes, bears ▪Found in North America, Europe, and Asia around 0° to 50° north latitude Chaparral ▪Generally receive 25 to 60 cm or less annual precipitation ▪A little more rain than deserts, primarily during mild winters ▪Summers long, hot, and arid ▪Dominant plants generally have hardened evergreen leaves ▪Animals include coyotes, jackrabbits, mule deer, lizards ▪Occur in California, South Grasslands ▪Large, rolling terrains of grasses, rich and fertile soil ▪Enough precipitation to keep deserts from forming but not enough to support forests (50 to 89 cm annually) ▪Dominated by grazers and burrowers such as bison, wild horses, prairie dogs, coyotes ▪Plants include buffalo grass, clovers, asters ▪Examples: North America’s shortgrass and tallgrass prairies, South ▪Between tropical Savanna rainforests and deserts ▪Enough precipitation to keep deserts from forming but not enough to support forests (38 to 64 cm annually) ▪Long, dry winters, short rainy seasons ▪Dominated by grazers and burrowers for example elephants, zebras, meerkats, lions, kangaroos ▪Plants include bermuda grass, acacia and eucalyptus ▪Receive less than 10 cm Deserts annual precipitation ▪Cover about 20% of the earth’s land area (and increasing) ▪Can be very hot during the day and very cold at night ▪Some are cold all the time ▪The plants and animals have adaptations to cope ▪Plants are spread out, spiny, thick outer layers ▪Animals include coyotes, jack rabbits, lizards, snakes, owls ▪Examples: Arabian, Atacama, Australia, Tropical Rainforests ▪Annual mean temperature of 25° C (77° F) ▪Regular, heavy rainfall ▪Humidity of at least 80% ▪Evergreen trees drop leaves and produce new ones year round ▪Litter does not accumulate because decomposition is rapid ▪Very thick and diverse plant and animal populations ▪Band around the equator, between the Tropic of Cancer and the Tropic of Capricorn ▪South America, West Freshwater ▪Ponds and Lakes ▪Streams and Rivers ▪Make up less than half of one percent of the world’s water ▪Supply half of the drinking water ▪Supply one third of the irrigation water Wetlands and Intertidal Zones ▪Marshes ▪Freshwater ▪Saltwater ▪Swamps ▪Bogs ▪Estuaries – where freshwater rivers flow into the sea ▪Intertidal Zones ▪Rocky shores ▪Sandy and Muddy shores ▪Plants include reeds, cattails, lilies, cypress ▪Animals include ducks, herons, beavers, moose, shrimp Ocean ▪Cover nearly three- fourths of the world’s surface ▪Supports more life forms than all the other biomes combined ▪The smallest creatures can be seen only with a microscope, the largest creature, the blue whale, can be up to 110 feet long Biosphere Made up of all the ecosyste ms on Earth Questions?
