A biome is “a major regional community of plants and
animals with similar life forms and environmental
conditions.”

snow) each year. Many of the world's
deserts are found within 30 degrees
latitude of the equator. You may have
heard about hot deserts like the Sahara
in northern Africa. The only precipitation
hot deserts get is a little bit of rain. But
there's another kind called a cold desert.
The only precipitation cold deserts get is
10 or fewer inches of snow in a year. The
Gobi Desert in China and Mongolia is a
cold desert and so is the Great Basin
Desert that stretches across Idaho,
Nevada, Oregon, and Utah in the U.S.

spaces that have very few trees. Grasslands
generally receive 10 to 30 inches of rain a year-enough to cultivate tall grass, but not enough
to sustain forests. In the United States, the
grasslands are mainly in the Midwest states.
Since grasslands soil is very rich, most of the
wild grasslands in the U.S. have been
converted to farm land. That's why the Midwest
is often referred to as the breadbasket of the
United States--most of our wheat, soybean,
and corn is grown there. African grasslands
are home to some of the most exotic animals
in the world: zebras, lions, warthogs,
ostriches, and elephants!

The taiga is the biome of the
needleleaf forest. Living in the taiga
is cold and lonely. Coldness and
food shortages make things very
difficult, mostly in the winter. Some
of the animals in the taiga hibernate
in the winter, some fly south if they
can, while some just cooperate with
the environment, which is very
difficult.

Temperate deciduous forests are forests in
cool, rainy areas; they have trees that lose
their leaves in Fall and regrow them in
Spring. Temperate deciduous forests are
found in the middle latitudes around the
globe and have four distinct seasons:
Spring, Summer, Fall, and Winter. In the
Northern Hemisphere, these forests are
found in North America, Europe, and Asia.
In the Southern Hemisphere, there are
smaller areas of these forests, in South
America, Africa, and Australia. The growing
season in these forests is about 6 months
long.

Rainforests are very dense, warm,
wet forests. They are havens for
millions of plants and animals.
Rainforests are extremely important
in the ecology of the Earth. The
plants of the rainforest generate
much of the Earth's oxygen.

Tundra is the coldest of all the biomes. It
is noted for its frost-molded landscapes,
extremely low temperatures, little
precipitation, poor nutrients, and short
growing seasons.
