Lithosphere
Hydrosphere
Atmosphere
Biosphere
None of the Earth’s systems are INDEPENDENT
instead they are INTERDEPENDENT
BIOSPHERE
The biosphere is:
• the portion of Earth that
supports living things
• unique to Earth
• dependent on the other
Earth Systems
What is the
scientific
way to say
“living”?
Biotic Factors- all
living things in an
ecosystem, such
as plants, animals,
fungi, &
microorganisms
What is the
scientific
way to say
“nonliving”?
-Abiotic factors are
all of the nonliving
things in an
ecosystem.
-The abiotic factors in
an ecosystem include:
water, soil,
temperature, air, wind,
elevation, source of
energy (usually the
Sun).
ECOLOGICAL LEVELS:
• Organism: one living
thing
• ex. lion
• Population: group of
organisms of the same
species living together
ex. A pride of lions
ECOLOGICAL LEVELS:
• Community:
collection of interacting
populations
ex. Lions and hyenas
• Ecosystem:
organisms and their
:
physical
surroundings
ex. Lions, hyenas,
water, sun
HABITAT
• A HABITAT: is the place where
an organism lives out its life
• Examples include the bottom of
a stream, a maple tree, a pond, a
park
• A habitat can change due to
natural and human causes
ECOSYSTEMS
• The biosphere’s systems are called:
ECOSYSTEMS
• All ecosystems must have a constant source
of energy (usually the sun) and cycles to
reuse raw materials.
• Examples are the water, nitrogen cycle, oxygenCO2 cycle
• An ecosystem is made up of all the
LIVING and NON-LIVING
components in a given area.
What are the
essential
An ecosystem
parts to all
is all of the
ecosystems? living and nonliving things in
an area.
HABITATS:
• Terrestrial: land
• Aquatic: water
• marine: salt water
• estuary: where fresh and salt
water mix
• Niche:role a species plays in
a community
