Biomes - joberts12

A Review
Biomes are a geographical area of distinctive
plant and animal groups adapted to the
climate and geography of the region. There
are over 30 Types of Biomes on Earth.
The plants and animals that live in a Biome
depend on its climate. Climate is the weather
that an area has had over a long period of
time, such as 30 years . The location of a
biome affects it’s climate.
Plants and animals are well suited to the
biome in which they live. Over time plants
adapt so they can get as much sunshine and
water as possible for making food.
For Example:
Some desert plants have long roots for
finding water deep in the soil
Animals also need to adapt in order to survive
in their biome. Some animals have bodies
that are specially suited to their home.
Animals that live in cold climates often have
thick fur to keep them warm. Many tropical
animals have large ears that give off extra
body heat and allow them to stay cool.
Abiotic, meaning not alive, are nonliving
factors that affect living organisms.
Examples: habitat (pond, lake, ocean, desert,
mountain) or weather such as temperature,
cloud cover, rain, snow, hurricanes, etc. are
abiotic factors.
Biotic means of or related to life. The prefix
'Bio' literally means life. Examples: Plants,
animals, fungi, protist and bacteria are all
biotic or living factors and other stuff like
competition, disease, and overpopulation are
all biotic factors .
Mississippi River- Abiotic
Heron- Biotic
Humidity- Abiotic
Rain- Abiotic
Algae- Biotic
Mosquito- Biotic
One tragedy to hit the taiga biome is acid rain.
Acid rain is formed when pollutants, such as
nitrogen oxide, from burning gas, and sulfur
dioxide, from burning coal, are released into the
air and mix with water vapor to form a cloud. If
these toxic clouds become heavy with water and
precipitation falls, the result can be devastating
to vegetation, animals, and the land. Since the
rain from these clouds is acidic, large spreads of
land can be destroyed. In some parts of
Scandinavia and Russia, vast areas of the taiga
have slowly died off because of acid rain.
Humans have cultivated many crops on
grassland soil. The soil is rich and almost
anything in it can grow if it is both used and
treated right. Poor agriculture practices can
ruin soil and turn a grassland into a lifeless,
barren land. If crops are not rotated properly,
all nutrients in the soil are stripped and poor
soil results. The soil then turns to dust and
nothing can grow in it for many years.
Logging of the temperate forests is a major
threat to the biome and everything thereby
inclusive. In North America loggers have
devastated many temperate forests. For instance,
of the ninety-five percent of forest covering the
state of Ohio in 1800, only fifteen percent
remains. deforestation not only affects the trees,
but it also affects every plant and animal living in
the area. Because of deforestation, the Carolina
parakeet became extinct in the early 1900's.
Other animals, like the Mississippi sandhill crane,
bears, woodland caribou, goshawks, wolves, fox,
and mountain lions, are also becoming
endangered .
