What is a biome? A biome is a geographic area with the same climate, flora, and fauna.
Abiotic factors Abiotic factors: never living things of the environment. • Examples: soil, air, light, temperature, water
Biotic factors Biotic factors: living or once living things of the environment. • Examples: people, bacteria, animals, plants, fungi, insects, dead plants and animals, etc.
Biomes of the World • Each of the world’s biomes has its own unique characteristics.
3 Main Climate Zones Polar to 66.5 N Temperate 66.5N to 23.5N Tropical 23.5 N to 23.5 S Temperate 66.5S to 23.5S Polar to 66.5 S
Polar Zone • Located from the Poles to 66.5 N and S. • Coldest Temperatures of all 3 zones • Tundra Biome • Taiga Biome
Temperate Zone • Located from 66.5 N and S to 23.5 N and S. • Change of Seasons • Experience hot and cold temperatures. • Temperate Forest • Prairie • Chaparral • Desert
Tropical Zone • Located from 23.5 N to 23.5 S. • Area along the equator. • Receives most solar radiation. • High temperatures/Precipitation varies • Desert • Rain forest • Savanna
Earth’s Climate Zones Complete the diagram: Draw the lines at the correct latitude and label the lines of latitude. Label the zones: Temperate, Tropical and Polar. Color the Tropical zone red, the Temperate zone green and the Polar zone blue.
Temperate Deciduous Forest • Temperature: -22 to 86º Fahrenheit • Precipitation: 24-60 inches annually • Characteristics: • Has 4 distinct seasons • You live here • Leaves change color in autumn • Zone: Temperate
Temperate Deciduous Forest • Flora: the plants of a biome • Examples: oak tree, maple tree, azaleas, shrubs, grasses • Fauna: the animals of a biome • Examples: ants, deer, turkeys, frogs, eagles • Interesting facts: • Deciduous trees lose their leaves to conserve water
Temperate Deciduous Forest • Covers 1/3 of the Earth’s area • Dominated by trees and woody vegetation • Precipitation is distributed evenly throughout the year • Animal life includes many things such as bears, deer,and rodents

Pictures of TDF fauna • American Bald Eagle • European Red Squirrel • White-tailed Deer
Tropical Rain Forest • Temperature: 75 to 85º Fahrenheit • Precipitation: 50-260+ inches annually • Characteristics: • 12 hours of daylight • 2 seasons: rainy and dry • Poor soil • Interesting facts: • Most diverse biome • Many plants there could be used for medicines. • 85% of the world’s TRF have been deforested.
Tropical Rain Forest • The Rain Forest is made of 3 layers: • The first layer is the canopy. • The second layer is the understory. • The third is the forest floor. • The Rain Forest contains about 45% of all animal species in the world making it the biome with highest biological diversity.
TRF Flora and Fauna • Flora: the plants of a biome • Examples: orchids, ferns, trees—would find many buttress trunks here • Fauna of the TRF is very shallow rooted. • Fauna: the animals of a biome • Examples: birds, bats, insects, frogs, & small mammals
Flora of the TRF BougainvilleaGenus: BougainvilleaSpecies: spectabilis Mangrove Forests TualangCommon Names: Mengaris, Honey Bee Tree, DëohGenus: KoompassiaSpecies: excelsa
Taiga/Boreal Forest/Coniferous Forest • Temperature: 14 to 57º Fahrenheit • Precipitation: 14-30 inches annually • Zone: Temperate • FYI: Current extensive logging may soon cause the taiga to disappear.
Taiga/Boreal Forest/Coniferous Forest • Characteristics: • Animals migrate, hibernate, or insulate to survive. • Cone shape of trees helps them shed snow & prevents damage to trees. • Soil is low in nutrients & high in acid. Why? • Found in the Northern Hemisphere near the polar region & very few people live there.
Taiga/Boreal Forest/Coniferous Forest • Interesting facts: • Find in Moscow, Toronto, etc. • Taiga is the Russian word for marshy pine forest. • It is home to bogs and ponds. • It has some permafrost but not as much as the tundra. • It occupies about 17% of the Earth’s land area.
Taiga/Boreal Forest/Coniferous Forest • Flora of the Taiga: • Include conifers (cone-producing plants) such as spruce, firs, and pines • Rarely see birch and aspen trees (deciduous trees) • Fauna of the Taiga: • Include moose, deer, bears, bobcats, squirrels, moles, eagles, birds, and insects
Taiga Flora Eastern Red CedarCommon Names: Red Cedar, grave yard treeGenus: JuniperusSpecies: virginiana Black SpruceCommon Names: Black Spruce, Bog Spruce, Swamp Spruce, épinette noireGenus: PiceaSpecies: mariana
Taiga Fauna Long-Eared OwlCommon Names: Cat OwlGenus: AisoSpecies: otus American Black BearGenus: UrsusSpecies: americanus Snowshoe RabbitCommon Names: Varying HareGenus: LepusSpecies: americanus WolverineGenus: GuloSpecies: luscus
Tropical Grassland/Savanna • Characteristics: • Has trees • Has wet and dry seasons • Dry season is always followed by fire and is necessary for survival of the savanna.
Temperate Grassland • Characteristics: • Few grasslands left due to clearing of land for farms—for croplands • Interesting facts: • Biome with the richest/most fertile soil
Temperate Grassland • Flora: grasses, flowers, and trees, only near water • Fauna: spiders, insects, rabbits, coyotes, mice, prairie dogs
Tropical Deserts • Temperature: -0.4 to 120º Fahrenheit • Precipitation: less than 20 inches annually • Zone: Tropical
Characteristics: Cover 1/5 of the Earth’s surface Have rich soil Hot and dry Interesting facts: 4 deserts in North America Plants have shallow roots near the soil surface, waxy coverings, & spiny leaves to conserve water. Sahara Desert in Africa is the world’s largest, covering over 3.5 million acres of land. Tropical Deserts
