What is a Biome? • A biome is group of ecosystems with similar climates, soil types, and organisms • All the biomes make up the Earth's biosphere.
Taiga Tundra Grassland Desert (temperate) Desert (Tropical Savanna Rain Forest Which biomes do you recognize?
Located at 50 to 60 degree latitudes Cold weather most of the year Thin nutrient-poor soil acidic soil Taiga Tundra Cold Terrestrial (Land) Biomes
Taiga (boreal forest) • Canada, Russia, Alaska • Short warm, wet summers; long cold dry winters • Coniferous Forests • Typical animals include foxes, moose, bears, and chipmunks
Tundra • Coldest of all biomes • Extremely short growing seasons (6 to 10 weeks) • Permafrost: Thin nutrient- poor soil • Long, cold, dark winters (6 to 10 months) • Low Precipitation • Snow provides insulation • Wildlife includes birds, reindeer, foxes, bears, seals, and walruses, caribou, wolves, and polar bears
Temperate Terrestrial Biomes • Grassland • Forest • Desert • 30 to 50 degree latitude • 4 seasons • Cooler than tropical • Pennsylvania is located in this biome
Temperate Grassland • Prairies in Central North America and the Steppes in N. Asia • Temperatures vary summer to winter • Moderate rain fall • Thick, nutrient-rich soil • Seasonal drought and occasional fires • Typical animal life includes jack rabbits, deer, foxes, coyotes, birds, and many other species
Temperate Forest • PA in this biome • Covers 1/3 of the Earth’s area • Dominated by trees and woody vegetation (Deciduous Trees) • Precipitation is distributed evenly throughout the year • Animal life includes many things such as bears, deer,and rodents
Temperate Desert • Deserts of Utah and Montana • Super-dry air • High daytime temperatures • Lots of wind • Typical animals include insects, reptiles, birds, and various mammals
Tropical Terrestrial Biomes • Found near the equator • Hotter than other biomes • 2 seasons • Savanna • Tropical Desert • Rain Forest
Savanna • Africa • Warm, hot climates • Thin nutrient-poor soil • Dry and rainy seasons • Seasonal fires help maintain balance • The Savannah is home to various large carnivores: lions, wildebeests, elephants, and zebra
Tropical Desert • Mojave, Sonoran in North America and the Sahara in Africa • Hot and dry; long summers, short winters • Super-dry air • High daytime temperatures • Few things live here • Small shrubs, cacti, insects, snakes, and small rodents
Rain Forest • Warm; very wet • Thick nutrient- poor acidic soil • Near the equator • More rain than any other biome • Millions of species live here.
Aquatic Ecosystems • Water covers nearly 75% of the Earth’s surface • There are numerous species of plants and animals who live here. • These range in size from microscopic organisms to the size of a 100 ft whale. • Oceans, marshes, wetlands, rivers, lakes
