and the _________ componentsnon-living
"living" "non-living"
• The carbon cycle is considered a

THE CARBON CYCLE
• Carbon dioxide is known as __________ gas temperature
greenhouse
greenhouse effect
How does carbon dioxide
in the atmosphere cause
the greenhouse effect?
• Too many green house gases (like CO2) cause a _______ greenhouse effect which leads to global _____________.
atmosphere
THE CARBON CYCLE
CO2
Solar radiationenters Earth’s atmosphere.
But some heat is prevented from escaping because it is
absorbed by greenhouse gases like CO2,
runawayclimate change
Some of the heat escapesinto space.
The radiation is absorbed by the atmosphere and
the Earth, which re-emitsthe radiation as heat.
which traps the heat in the atmosphere.
THE CARBON CYCLE
• Through the processes of living and dying, producers, consumersand decomposers help cycle carbon through the biotic and abioticcomponents of the environment.
• Detritus is the _____ and _______ of once living organisms.
