What is a biome?What is a biome?

A biome is a geographic area with the same climate, flora, and fauna.

Page 3: Terrestrial Biomes

Abiotic factorsAbiotic factors

Abiotic factors: never living things of the environment.

– Examples: soil, air, light, temperature, water

Page 4: Terrestrial Biomes

Biotic factorsBiotic factors

Biotic factors: living or once living things of the environment.

Examples: people, bacteria, animals, plants, fungi, insects, dead plants and animals, etc.

Temperate Deciduous ForestTemperate Deciduous Forest

Temperature: -22 to 86º FahrenheitPrecipitation: 24-60 inches annuallyCharacteristics:

– Has 4 distinct seasons– You live here– Leaves change color in autumn

Zone: Temperate

Page 16: Terrestrial Biomes

Temperate Deciduous ForestTemperate 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

Page 17: Terrestrial Biomes

Temperate Deciduous ForestTemperate 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

Rain ForestRain Forest

Page 22: Terrestrial Biomes

Tropical Rain ForestTropical 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.

Page 23: Terrestrial Biomes

Tropical Rain ForestTropical Rain ForestThe 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.

Taiga

Page 29: Terrestrial Biomes

Taiga/Boreal Forest/Coniferous Taiga/Boreal Forest/Coniferous ForestForest

Temperature: 14 to 57º Fahrenheit

Precipitation: 14-30 inches annually

Zone: Temperate

FYI: Current extensive logging may soon cause the taiga to disappear.

Page 30: Terrestrial Biomes

Taiga/Boreal Forest/Coniferous Taiga/Boreal Forest/Coniferous ForestForest

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.

Page 31: Terrestrial Biomes

Taiga/Boreal Forest/Coniferous Taiga/Boreal Forest/Coniferous ForestForest

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.

Page 32: Terrestrial Biomes

Taiga/Boreal Forest/Coniferous Taiga/Boreal Forest/Coniferous ForestForest

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

Tropical DesertsTropical DesertsCharacteristics:

– 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.

Temperature: 10-59º Fahrenheit

Precipitation: 12 inches annually

Zone: temperate

Page 66: Terrestrial Biomes

Mountain/AlpineMountain/AlpineCharacteristics:

– Too cold and too much UV from sun, causing few organisms to live there

– Found at elevations of 10,000 feet– Animals migrate, hibernate, or insulate

to survive the cold of this biome.– Animals have shorter tails, legs, & ears

to reduce heat loss. – Animals have larger lungs and more red

blood cells

Page 67: Terrestrial Biomes

Mountain/AlpineMountain/Alpine Interesting facts:

– Very dry– Cover 16% of Earth’s surface area– Sandy, rocky, well drained soil– Temperature can go from warm to freezing

in a few hours to a day– Rainshadow effect– Every 3,280 feet increase in elevation = 18

degree drop in temperature

Page 68: Terrestrial Biomes

Mountain flora and faunaMountain flora and fauna

Not many plants because of little carbon dioxide.

Find small plants near the ground and dwarf trees, grasses, heaths, and shrubs.

Fauna include goats, sheep, elk, beetles, grasshoppers, and butterflies.
