Overview
What
is a biome?
What do you know about biomes? To find out, try the online
activity "Planning a Trip to Funworld." Or, try one of
the other great activities on biomes. You may have questions. Don't
worry. We gathered some facts about biomes.
Have
you ever been to a zoo? Have you noticed the different parts of
a zoo? Do the penguins live with the eagles? Do the zebras live
with the whales? The answer to both of these questions is "no."
These animals come from different parts of the world. For example,
penguins live in very cold places. It is much warmer where eagles
live. Zookeepers try to make the animals' home in the zoo like their
home in the wild. To do this, zookeepers need to know about biomes.
There
are many types of plants and animals on Earth. Certain plants and
animals are often found grouped together. Each of these groups is
only found naturally in certain places on Earth. In these places,
the plants and animals interact with each other. They make up ecological
communities. These communities
of plants and animals are called biomes. For example, panda bears
and bamboo trees are often found together. They live in the mountains
in southwestern China. That is their biome.
The
plants and animals that make up a biome are determined by climate.
Climate is a region's long-term pattern of weather. It is the average
range of temperature and amount of rain or snow an area receives.
Some biomes are hot. Some are cold. Some are wet. Some are dry.
Plants
and animals in each biome have special traits.
These traits help them live where they do. For example, polar bears
have a lot of fat and thick fur. The fat and thick fur keep them
warm. These features allow polar bears to live in cold regions on
Earth. At the same time, these features make it impossible for them
to survive in hot regions.
The
plants, animals, and climate of a region define a biome. Scientists
classify Earth's biomes in many different ways. Some divide Earth
into many small biomes. These biomes may be only slightly different
from each other. Other scientists, however, divide Earth's surface
into just a few major biomes. For example, a group of students at
the University of California, Berkeley created a list of The
World's Biomes. This list includes only five major biomes. These
biomes are forests, deserts, grasslands, aquatic, and tundra. The
University of California students divide each of the five major
biomes into smaller biomes. They list thirteen sub-divisions within
these five major biomes. A sixth major biome that many scientists
list is the chaparral.
Six
of the major biomes on Earth are forests,
deserts, grasslands,
aquatic, tundra,
and the chaparral.
