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.
