Introduction to Biomes

Biomes are dependent on two very

important environmental factors:

Average Temperature

Average Rainfall

Biomes are named after the dominant type of vegetation (plants) associated with

large land areas.

The three major land biomes are:

(1) Deserts, (2) Grasslands, (3) Forests

Mind Stretcher 10/4/161. Which of the following is NOT a way that nitrogen cycles

through the environment?

Decomposition releases nitrogen into the soil.

Plant roots take up nitrogen from the soil.

Bacteria in the soil convert nitrogen back to a gas.

Nitrogen is stored in fossil fuels.

2. Why is the carbon cycle important to living things?

It transports a material needed by all living things.

It converts nitrogen to a usable form.

It converts carbon from a liquid to a gas.

It transports wastes in organisms.

Forests have these qualities:

1. A wide variety of plants, dominated by

trees.

2. Provides a variety of habitats for a

Tropical Rain Forest: constant hot temp., high

humidity, daily afternoon rains, poor soil,

hardwood trees, most animals live in the

canopy, most biologically diverse

Animals- monkeys, birds of paradise, sloth,

tons of insects, snakes, gorillas

Types of forests:

CLIMATE:

Precipitation-

• up to 400 cm yearly (157.5 inches)

Average Temperature-

• 20-34 degrees C (temperature is from night to day)

• (68-93 degrees F)

Types of forests:

Temperate Deciduous: moderate/average

temperatures which change a lot during

4 seasons, abundant precipitation, deciduous

trees lose their leaves each fall, soils are rich in

nutrients

Animals- deer, porcupine, hawks, raccoons, frogs,

turtles, owls, red foxes

Quick Write(Use complete sentences on an index card)

Like the biomes of all of the southeastern

United States, Georgia’s biome is temperate

deciduous forest. Describe three characteristics

of a temperate deciduous forest.

“A temperate deciduous forest….”

Mind Stretcher –

1. Which of the following best

describes the graph?

Tropical, Temperate or

Polar?

Forest, Grassland, or Desert?

2. What biome do you think

this data is from?

Tropical Rain Forest

Grasslands have these qualities:

1. Precipitation is high enough to allow grass to

grow.

2. Droughts and fires prevent permanent forests.

3. Home to large herbivores and many burrowing

animals

Types of Grasslands

Savanna (Tropical Grassland): high avg. temps. with

a prolonged dry season of 4-6 months. Rest of the

year is a wet season. Scattered clumps of trees.

Animals- zebra, lion, leopard, giraffe, elephant, rhino,

warthogs, etc. (Think LION KING)

CLIMATE:

Precipitation-

• 150 cm yearly (59 inches)

Average Temperature-

• Dry Season: 34ºC (93ºF)

• Wet Season: 16ºC (61ºF)

Prairie (Temperate Grasslands): Strong,

continuous winds & rapid evaporation; Has

grass but few trees due to

fires/grazing/drought

Animals- bison, coyote, prairie dogs,

pocket gophers

Types of Grasslands

CLIMATE:

Precipitation-

• 25cm-75 cm yearly (10-29 inches)

Average Temperature-

• Summer: 30ºC (86ºF)

• Winter: 0ºC (32ºF)

Tundra (Polar Grasslands): Most of the year the

climate is extremely cold with high winds & snow

cover. Winters are long and low precipitation

(mostly snow); Alpine tundra= top of mountains

Permafrost = (frozen soil)

Animals- mosquitoes, birds, musk oxen, arctic

wolves, caribou

Plants- shallow rooted plants, grasses, shrubs,

mosses, lichens

Types of Grasslands

CLIMATE:

Precipitation-

• 30cm-50 cm yearly (10-20 inches)

Average Temperature-

• Summer: 12ºC (54ºF)

• Winter: -26ºC (-15ºF)

DEMONSTRATION with ICE WATER

Animal Adaptations…BRRR!

Animal Adaptations…BRRR!

How this lab shows how animals stay warm even

in cold climates:

The shortening (vegetable fat) acts just like the

layer of fat that is hidden under the skin of

animals such as walruses, whales, and penguins

who live in cold climates. The fat is an insulator

meaning it does not allow heat or cold to move

in or out of an object quickly. The fat holds the

body heat in so the animal is able to stay warm.

Based on the activity Penguin Undercoat from VanCleave (2000).
