Lesson 6.1 – Organization of
the Biosphere
I can describe the levels of organization in the biosphere. I can
identify biotic and abiotic factors in an ecosystem. (3e)
1. All organisms live in and
depend on their environment.
a. The scene you described
above would be considered
your environment.
2. The parts of the Earth that
contain living things are
together called the biosphere.
a. All land and water as well
as the lowest part of the
atmosphere are part of the
biosphere because
living things are found in all
of these places.
I can describe the levels of organization in the biosphere. I can
identify biotic and abiotic factors in an ecosystem. (3e)
3. The biosphere is divided into
smaller parts called ecosystems.
a. Ecosystems include all the
living and nonliving parts of a
certain environment.
i. The living parts are called
the biotic factors.
1. In a pond, the biotic
factors would be
frogs, fish, plants, algae,
etc.
2. Animal remains (dead
animals) and animal waste
(poop) are considered to
be biotic.
I can describe the levels of organization in the biosphere. I can
identify biotic and abiotic factors in an ecosystem. (3e)
ii. The nonliving parts are
called the
abiotic factors.
1. In the pond example, the
abiotic factors would be the
light, temperature, weather,
soil and water.
iii. Remember, “bio” means
life and “a” means
without.
I can describe the levels of organization in the biosphere. I can
identify biotic and abiotic factors in an ecosystem. (3e)
4. Each ecosystem contains different habitats which
are the places that different organisms live.
a. A habitat provides all the biotic and abiotic
factors that an organism needs to live.
I can describe the levels of organization in the biosphere. I can
identify biotic and abiotic factors in an ecosystem. (3e)
5. Each organism has a specific role (job) that it does
in its environment. This is referred to as its niche
(“nitch” or “neesh”)
a. In the pond, mosquitos lay eggs on the surface
of the water and frogs eat some of these mosquito
eggs. Animals that die are broken down by fungi
and bacteria.

(5 Questions)
1. A scientist is studying all of the
different ecosystems that make
up the Earth. Which of this is a
better way to describe this?
A. She is studying the habitat
B. She is studying the biosphere
C. She is studying the niche
D. She is studying the community
2. Which of the
following
describes what is
shown at the
right?
A. A biosphere
B.
An ecosystem
C. A biotic factor
D. An abiotic
factor
3. Which of these is NOT an
example of a biotic factor?
A. Droppings of a bear
B. The carcass of a dead salmon
C. Shale river rock
D. A bald eagle hatchling
Caves are teeming with life. Bats lay droppings
which attract various insects which they can eat.
Silk worms produce their own light to attract
insects. Insects feed off of dead organisms,
helping to break them down.
4. Which of these is an example of a biotic factor
found in caves?
A.
Silk worms found on the walls
B.
Insects eating dead organisms
C.
Sedimentary rock walls
D.
A lack of sunlight for plant life
