Background Information
In deciduous forests there are five different zones. The first zone is the Tree
Stratum zone. The Tree Stratum zone contains such trees as oak, beech, maple,
chestnut hickory, elm, basswood, linden, walnut, and sweet gum trees. This
zone has height ranges between 60 feet and 100 feet. The small tree and
sapling zone is the second zone. This zone has young, and short trees. The third
zone is called the shrub zone. Some of the shrubs in this zone are
rhododendrons, azaleas, mountain laurel, and huckleberries. The Herb zone is
the fourth zone. It contains short plants such as herbal plants. The final zone is
the Ground zone. It contains lichen, club mosses, and true mosses. The
deciduous forest has four distinct seasons, spring, summer, autumn, and winter.
In the autumn the leaves change color. During the winter months the trees lose
their leaves. The animals adapt to the climate by hibernating in the winter and
living off the land in the other three seasons. The animals have adapted to the
land by trying the plants in the forest to see if they are good to eat for a good
supply of food. Also the trees provide shelter for them. Animal use the trees for
food and a water sources. Most of the animals are camouflaged to look like the
ground.
The plants have adapted to the forests by leaning toward the sun. Soaking up
the nutrients in the ground is also a way of adaptation.

American Bald
The American Bald Eagle is a
Eagle:
menacing bird with a white head. It is
the national symbol of the US. The
female eagle is larger than the male.
They are raptors and eat smaller birds.
American Black
Bear
The American black bear is a
dangerous animal that interacts with
growls. The Black Bear hides in
winters.

Beaver
•
Beavers are small rodents that
are semi aquatic. They live in
small lodges alongside bodies of
water. They mainly eat tree barks,
twigs, leaves and water plants.
Brown Bear
Brown bears are large and stay in
cool regions. They are omnivores
and eat fruits and fish. They are
easily awakened.
A. Ronshausen
Coyote
Although it is a fact that coyotes
can live anywhere, deciduous
forests is one of its favourite
dwellings. They hunt alone for
their food. It eats small
mammals, reptiles mice and
fruit.
Duckbilled Platypus
PlPlatypus
They are mainly found in
Australian deciduous forests.
They are as large as half of a
house cat. They are one of the
A. Ronshausen
rare mammals that lay eggs.
Red tailed Hawk
•
Hawk
One of the most spread
species of hawks is the redtailed hawk. They are
carnivores and eat
mammals, rodents and
insects. They are found in
taigas.
Eastern Rabbit
Cottontail
Rabbit
Unlike others, cottontail rabbits
require loads of water during
winter season than the summer.
Other rabbits eat snowA.in
winter.

Nightingale
Nightingales have incredibly
melodious voices in which they
sing mostly during the night hours.
They eat insects, larvae and fruits.
European Red Squirrel
The red squirrels are
omnivores and hibernate during
winter. They live up to 15 years.
They are commonly eaten by
eagles, hawks, bears and
coyotes.

Plant Life
•
The deciduous forest is mostly made up
of deciduous trees. These are trees that
lose their leaves at a certain time each year
and then later grow new leaves to replace
them. Deciduous trees lose their leaves in
autumn. However, before the leaves die,
the food material that they contain is drawn
back into twigs and branches and is stored
there to be used in the spring. Losing its
leaves helps the tree conserve water in the
winter. Some examples of deciduous trees
are ash, beech, birch, maple, oak,
hickories, aspens, and larch trees. The

Physical Landscape

Landscape
Deciduous forests exist in areas with a moderate
amount of precipitation, where temperatures in these
types of areas. Deciduous forests in general have long
summers and short winters. However, the most visible
feature of a deciduous forest is that they have a lot of
deciduous trees in them, which are trees that fall off at
fall. Over 150 cm of rain and other precipitation falls
every year. A lot of animals live in a deciduous forest;
there are cougars, bears, deer, foxes, owls, opossums,
birds, skunks, rodents, birds, insects and the many
types of trees, bushes, and flowers.

Human Influences
•
A lot of human population live in biomes,
people are cutting down trees, making animals lose
their habitat and people are also polluting water
and air. Our current human interaction with the
forest can be beneficial and destructive. Humans
are killing animals for food. People like you hike or
camp in the forest, the way people are destructive
to the forest, such as a forest fire, which can be
caused by humans. Although some people try to
protect the forest, poachers try to kill the animals in
the forest. Animals are also losing their homes
because of more homes built by humans.

Questions
A. Ronshausen
• Is there a certain plant that only
exist in deciduous forest?
• There is not any species that only exist in deciduous
forest. It has normal plants like evergreen trees and
more.
• Are the plants endangered by
other species? Give an example
to support your idea.
• Yes they are endangered by other species because
there are a lot of consumers that are consuming the
plants and are endangered by human needs. One of
my examples is humans cutting down trees for shelter.
A. Ronshausen
• If some of the deciduous trees
were cut down, what would
happen?
•
If some of the trees were cut down in a deciduous forest,
then that part of the biome would slowly clear out of animals,
and the flowers there would die because there is no home for
bees to live in. Therefore, there would be no bees to pollinate
the flowers.
•
• What would happen if there were too
many predators in a deciduous forest?
•
When there is are too many predators in a biome, the
predators will greatly decrease the number of prey, so they will
eventually get hungry and die, and then the number of prey will
rapidly multiply, eating all the plants and there goes your
biome.
A. Ronshausen
• What do you think would happen
to the Deciduous forest if humans
keep polluting the earth?
• There can be a possible chance for these results. One the forest will
be cut down and animals will be forced to flee. Two the forest will root
from pollution and deforestation. Three the forest will live and some
animals will live.
• Because of humans what forests
like the Deciduous forest suffering
of?
• They are suffering from deforestation, pollution, habitats and a lot of
other things.

•
What would happen if something
were to change the landscape of a
particular biome?
The habitat of the animals is disrupted due to the
cause of possible disasters. These possible natural
disasters can be earthquakes, tornadoes etc.
For example: If an earthquake occurs in a
deciduous forest it will weaken majority of the trees
eventually making them fall. As the trees will die, many
species that are inhabited in these trees will be
homeless and injured. These species will eventually
die off starvation.
A. Ronshausen
What if the temperature were to
rise or lower significantly?
•
•
•
If the temperature were to rise/lower significantly in a
small period of time, the animals in the forest will have
difficulty adjusting to the frequent and severe changes in
their lifestyle and environment. Some animals may not be
able to adjust to these frequent changes and might die.
Additionally, some animals may also choose to migrate to a
place where the temperature stays stable throughout the
year.
For example: If the summers are extremely hot and
winters are extremely cold, species such as birds may not
be able to adapt to these severe frequent changes and may
die off. They may also migrate to a place where the
temperature stays constant throughout the year.
A. Ronshausen
What if a developer wants to build
on the land; what if an animal
becomes extinct?
•
If a developer wants to build on the land, he will
cut down trees. This will make animals that depend on
these trees, such as squirrels, birds, worms, etc.
homeless. These animals will eventually become
extinct. This animal extinction process will greatly
affect many animals that live in the biome. When a
smaller animal is extinct, the animals that are higher on
that particular food chain will start dying due to
starvation. The extinction (due to starvation) will
continue up the food chain, eventually the top
consumer will also die off starvation. Therefore, if an
animal becomes extinct, all of the animals in the food
chain will become extinct and the food chain will end.
A. Ronshausen
What if a plant were destroyed, or if the rainfall greatly
increases or decreases?
•
If a plant was destroyed, it would affect the animals that
are inhabited in it. For example, small animals will not get
enough nutrients from the primary producer (plant) to
support themselves. This malnutrition will continue up the
food chain, eventually weakening the top consumer.
•
If the rainfall greatly increases/decreases, it will have a
huge effect on the soil and plants. If an area receives very
little rain, the soil of the area eventually loosens and is
eroded by wind. Also, the trees don’t get enough nutrients
(needed from water) and eventually start dying. Over time,
this loosen soil turns into a desert. On the other hand, if an
area receives very heavy rain, soil erosion occurs due to the
excess amount of water. It inhibits the growth of the plants.

Question #1:
What are the four different species of animals
found in a Deciduous Forest Biome?
Answer: The four different species of animals found in a
Deciduous Forest Biome are: Mammals, Birds, Insects
and Reptiles.
For Example: A mammal in a deciduous forest is the
“American Black Bear.”
An example for the bird species would be the
“Nightingale.”
Examples for Insects and Reptiles would be the a
“Butterfly” and a “Turtle.”
A. Ronshausen
Question #2:
•
How do animals in the temperate deciduous forest
defend themselves?
Animals in the temperate deciduous forest defend
themselves by the environment they live in and by there
adaptations that they have. Animals in temperate deciduous
forests also have to adapt to the changing seasons. They
must be able to cope with cold winters when food is in short
supply. Migration and hibernation are two adaptations used
by the animals in this biome.
A. Ronshausen
What would happen if something were to
change the landscape of a particular biome?
•
The food chain would change causing
harm to the environment and it will cause lack
of oxygen.
What if the temperature
were to rise or lower
significantly?
If it was too hot really sudden the trees would
turn Orange and it wont affect these trees if it
were too cold.
A. Ronshausen
What if a developer wants to build on the
land; what if an animal becomes extinct?
•
If this happens the area will lack of oxygen
and animals will die from that too.
What if a plant were destroyed, or if
the rainfall greatly increases or
decreases?
If a plant were to be destroyed the animal that eats
it would extinct and soon every organism will extinct
in this region. If the rainfall would decrease all the
plants will die.
