Terrestrial Biomes
What is a biome? A biome is a geographic area with the same climate, flora, and fauna.
Abiotic factors: never living things of the environment. – Examples: soil, air, light, temperature, water
Biotic factors: living or once living things of the environment. l Examples: people, bacteria, animals, plants, fungi, insects, dead plants and animals, etc.
Levels of Organization
Terrestrial Biomes: differ by location, plants, and animals l l l l l Temperate/Deciduous Forest (TDF) Tropical Rain Forest (TRF) Taiga/Boreal Forest/Coniferous Forest Tropical Grassland/Savanna Temperate Grassland/Prairie Tropical Desert Cold Desert Chaparral Tundra Mountain
Biomes of the World l Each of the world’s biomes has its own unique characteristics.
3 Main Climate Zones Polar to 66. 5 N Temperate 66. 5 N to 23. 5 N Tropical 23. 5 N to 23. 5 S Temperate 66. 5 S to 23. 5 S Polar to 66. 5 S
Polar Zone l Located from the Poles to 66. 5 N and S. l Coldest Temperatures of all 3 zones l Tundra Biome l Taiga Biome
Temperate Zone Located from 66. 5 N and S to 23. 5 N and S. l Change of Seasons l Experience hot and cold temperatures. l Temperate Forest l Prairie l Chaparral l Desert l
Tropical Zone l Located from 23. 5 N to 23. 5 S. l Area along the equator. l Receives most solar radiation. l High temperatures/Precipitation varies l Desert l Rain forest l 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 l Temperature: -22 to 86º Fahrenheit l Precipitation: 24 -60 inches annually l Characteristics: – Has 4 distinct seasons – You live here – Leaves change color in autumn l Zone: Temperate
Temperate Deciduous Forest l Flora: the plants of a biome – Examples: oak tree, maple tree, azaleas, shrubs, grasses l Fauna: the animals of a biome – Examples: ants, deer, turkeys, frogs, eagles l Interesting facts: – Deciduous trees lose their leaves to conserve water
Temperate Deciduous Forest Covers 1/3 of the Earth’s area l Dominated by trees and woody vegetation l Precipitation is distributed evenly throughout the year l Animal life includes many things such as bears, deer, and rodents l

Rain Forest
Tropical Rain Forest Temperature: 75 to 85º Fahrenheit l Precipitation: 50 -260+ inches annually l l Characteristics: – 12 hours of daylight – 2 seasons: rainy and dry – Poor soil l 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 l 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. l 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 l Flora: the plants of a biome – Examples: orchids, ferns, trees—would find many buttress trunks here – Fauna of the TRF is very shallow rooted. l Fauna: the animals of a biome – Examples: birds, bats, insects, frogs, & small mammals

Tropical Deserts l Temperature: -0. 4 to 120º Fahrenheit l Precipitation: less than 20 inches annually l Zone: Tropical
Tropical Deserts l Characteristics: – Cover 1/5 of the Earth’s surface – Have rich soil – Hot and dry l 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.
