Biomes A biome is a large ecosystem where plants,

animals, insects, and people live in a certain type of climate

Biome Characteristic: Rainforests2 types: Topical and Temperate

Most trees flare at the base

Vegetation is dense (tall and green)

Rich in diversity (especially in tropical rainforests)

Precipitation and Climate 

Lush and wet

Rainfall is regular throughout the year (80-400 inches of rainfall

per year for tropical)

Tropical rainforests are warm and moist; while temperate

rainforests are cool. 

Biome Characteristic: TundraArctic tundra is located at the poles

Animals are adapted to handle cold winters and to breed and raise

young quickly in the very short and cool summers.

The soil is often frozen. Permafrost, or permanent ice, usually exists

within a meter of the surface.

Precipitation and Climate 

 The average annual temperature is only

10 to 20F (-12C to -6C)

Water is unavailable during most of

the year. 

Annual precipitation is very low, usually

less than 10 inches (25 centimeters).

Biome Characteristic: Taiga The largest biome in the world.

Winters are cold. Summers are warm. Lots of conifers grow here.

Prone to wildfires. Many trees have adapted to this by growing

thick bark

Precipitation and Climate 

 The average temperature is below freezing for six months of the

year.

Total yearly precipitation in the taiga is 12 - 33 inches (30 - 85

centimeters).

Although the cold winters have some snowfall, most of the

precipitation comes during the warm, humid summer months.  

Biome Characteristic: Desert land of extremes: extreme heat and extreme

dryness but sudden flash floods and cold nights.

have so few trees and other vegetation

Precipitation and Climate 

 Deserts are usually very, very dry.

Even the wettest deserts get less than ten inches of

precipitation a year

there may be only a few periods of rains per year

with a lot of time between rains

Biome Characteristic: Temperate Deciduous Has four seasons of winter, spring, summer, and fall.

Animals and plants have special adaptations to cope with

yearly/seasonal changes.

The word "deciduous" means exactly what the leaves on

these trees do: change color in autumn, fall off in the

winter, and grow back again in the spring.

Precipitation and Climate 

Gets the second-most amount of rainfall per year

Average temperature of the forest is about 50 degrees

Fahrenheit.

Biome Characteristic: Grasslands Big open spaces

There are not many bushes in the grassland. Trees are

found only by rivers and streams. The grassland seems

like an endless ocean of grass

Grassland soil tends to be deep and fertile.

Found on every continent except Antarctica

Precipitation and Climate 

 Grasslands receive about 10 to 30 inches of rain per year

If they received more rain, the grasslands would become a

forest. If they received less, they would become a desert.

Biome Characteristic: Marine Marine regions cover about three-fourths of

the Earth's surface and include oceans, coral

reefs, and estuaries.

Marine algae supply much of the world's

oxygen supply and take in a huge amount of

atmospheric carbon dioxide.

The evaporation of the seawater provides

rainwater for the land.

Biome Characteristic: Freshwater Freshwater is defined as having a low salt concentration

— usually less than 1%.

Plants and animals in freshwater regions are adjusted to

the low salt content and would not be able to survive in

areas of high salt concentration

You'll find a wide variety of animal life in or around fresh

water ecosystems...aquatic birds... amphibians..mammals

and of course, a wide variety of fish.  And the water

cycle is very important to fresh water ecosystems

My BiomesTerrestrialMy Terrestrial Biome is Tropical

Rainforest. A Tropical Biome

has wet and dry climate. It is

rich in biodiversity

The rainforests are home to more

worldwide species than all

other biomes added together.

About 80 percent of the

world's known biodiversity

could be found in forests.

AquaticMy Aquatic Biome is Marine

Coral reef. Marine ecosystems

are very important for the

overall health of both marine

and terrestrial environments.

In addition, other marine

ecosystems such as coral

reefs, provide food and

shelter to the highest levels of

marine diversity in the world.

My BiomesTerrestrialThe leafy tops of tall trees -

extending from 50 to 85 metres

above the forest floor - forms an

understory. Organic matter that

falls to the forest floor quickly

decomposes, and the nutrients.

Rainforests are partly

characterized by high rainfall.

This often results in poor soils

due to leaching of soluble

nutrients.

AquaticCoral reefs are underwater structures

made from calcium carbonate

secreted by corals. Corals are

colonies of tiny living animals found

in marine waters that contain few

nutrients.

Most coral reefs are built from stony

corals, which in turn consist of polyps

that cluster in groups. But unlike sea

anemones, coral polyps secrete hard

carbonate exoskeletons which

support and protect their bodies.

Reefs grow best in warm, shallow,

clear, sunny and agitated waters.
