DECIDUOUS FOREST
WILLIAM D., CATIE W., JASLEEN P.
Where is ecosystem located?
 Mostly in the Northern Hemisphere
 Few in the Southern Hemisphere
 North America, Asia, and Europe
 Connecticut!
Describe the abiotic factors of
your ecosystem
 Really rich soil
 Temperatures average about 50 degrees Fahrenheit
 The four seasons are: Fall, Winter, Spring, and Summer
Producer: Tree. How does your
producer rely on other organisms in
the Deciduous forest to survive?
 Burying beetles bury dead animals, decomposing bodies
provide nutrients
 Earthworms scoot through the dirt to provide nutrients
 In the winter the leaves die, fall, and decompose to
provide nutrients
How do other organisms of your
ecosystem rely on your producer to
survive?
 Rotting plants turn into soil
 Caterpillars need branches to climb on and get leaves.
 Tops of the trees form a canopy, monkeys and birds live
up there
 Baby bears climb trees to be safe
 Beavers make their homes by chewing down trees
 Trees make air for people to survive
How do humans affect your
ecosystem?
 Humans cut down trees
 Littering - garbage covers the forest floor
 Pollution in some rivers and air
 People are trying to help make the forest a better place
Choose one biotic or abiotic factor in
your ecosystem & describe how a
change in one of these could affect
your ecosystem.
•
Change: Pollution
•
Worms make the soil cleaner and die because of
pollution
•
Without trees there are no homes for the beavers, no
hiding spots for bears
•
Without trees air would be polluted for humans
Other interesting facts:
•
People depend on trees for air
•
Acid rain comes from pollution
•
Forests in Eastern Europe are dying because of acid rain
•
Skunk cabbage is one of the first plants to emerge in
spring
• When you cut down a tree you can count the rings on
the tree to see how old it is
• You can determine what the weather was like by how
far apart the rings are on the tree
