Transcript The Carbon Cycle

COPY INTO GLOSSARY
PHOTOSYNTHESIS
This is a process by which plants use light energy,
water and CO2 to produce sugars., their food
RESPIRATION
All animals and plants do this, it needs O2 and
produces energy
CO2 A gas with carbon in it.
FOSSIL FUELS
Oil and coal are these, they release carbon
dioxide when burnt

Focus: Nature’s Cycles
Objective: 6.L.1.2 review the water
cycle and analyze the role of
plants and animals in the carbon
cycle

Lithosphere – includes Earth’s crust or
surface, and the upper mantle
Atmosphere – made of the gases that
surround Earth, weather occurs in the
atmosphere
Hydrosphere – includes all the water
found on Earth
Biosphere – includes all the living things
on Earth and the environments in
which they live

The Carbon Cycle
All life is based on the element
carbon.
Carbon is in…..
•all living things
•the atmosphere
•layers under ocean floor
•fossil fuels (coal, oil, gas)
Every living thing contains
carbon.
Carbon is always being cycled through the
environment (from plants and animals to the
air and ground)
This is how all living things have

the air INTO plants and animals?
Carbon dioxide (CO2)
moves into plants by
photosynthesis
Carbon moves into
animals by eating
plants or other
animals
Carbon moves from the air into plants
by photosynthesis!
Plants take in carbon dioxide (CO2) through their
leaves. They use CO2 to make their food. Then,
plants give out oxygen (O2) in a process called
photosynthesis.
Photosynthesis:
When plants take
in carbon dioxide
(CO2) and change
it into oxygen (O2)
(CO2) => (O2)
Draw
How does carbon dioxide move
INTO the air FROM animals?
All living things breathe.
This is called respiration.
During respiration,
animals take in oxygen
(O2) and give out carbon
dioxide (CO2).

GLOBAL WARMING: A result of
TOO MUCH carbon in the air!
Too much
carbon in the
atmosphere is
bad for the
Earth. It traps in
heat and causes
global warming.
Burning fossil fuels produces carbon dioxide

How does TOO MUCH carbon
move into the air? “Burning coal, oil,
and other fossil
fuels releases
heat-trapping gas,
such as carbon
dioxide (CO2), into
the atmosphere.”
Burning fossil fuels produces carbon dioxide
Human activities
We burn lots of fossil fuels
-Transportation (cars, busses, etc.)
-Heating
-Cooking
-Electricity
-Factories
All of this releases lots of carbon dioxide CO2 into
the air.
We are adding carbon to the air faster than it can
be removed through photosynthesis.
Because of this, there is more carbon
dioxide today than there has ever been!
Human Activities
Deforestation (Cutting down lots
of trees)
Allows too much carbon dioxide
(CO2) into the air.
Less trees means less
photosynthesis, so more CO2.
What can we do??
Human Activity that can REDUCE
(decrease) the amount of Carbon
• USE LESS ELECTRICITY
– Electricity is one of the biggest producers
of carbon. Every time you make toast or
turn on the TV, you are adding to global
warming.
– Turn it off when not in use (lights, TV,
DVD player, computer, etc....)
• Recycle paper and plant more trees

A) PHOTOSYNTHESIS
C) CO2
B) RESPIRATION
D) FOSSIL FUELS
1) All animals and plants do this,
it needs O2 and produces energy
E) A CYCLE
5) A gas with
carbon in it.
2) This has no beginning or end, it keeps going!
3) Oil and coal are these, they
release carbon dioxide when burnt
4) This is a process by which some
Living things use CO2 to produce sugars.
