TRANSCRIPT
THE OXYGEN-CARBON DIOXIDE CYCLE.
Oxygen-Carbon Dioxide CycleBoth are important GASSES to all living
things.Unlike water which always stays water,
oxygen (O2) and carbon dioxide (CO2) convert back and forth as they cycle on the planet.
Carbon-dioxide
Carbon-dioxide is present in very small amounts in air. Yet , it plays a vital role in the living world through theprocess of photosynthesis.
CARBON

Plants and animals
Carbon moves around in different parts of the earth. This is known as the Carbon Cycle.
CARBON CYCLE
CO2 Cycle - diagram
ANIMAL CONTRIBUTION During respiration
(breathing), animals inhale oxygen (O2) and convert it to carbon dioxide (CO2).
PLANT CONTRIBUTION During
photosynthesis (the process where plants make food for themselves) plants breathe in carbon dioxide (CO2) and exhale oxygen (O2).
DECOMPOSERS
Dead organic material contains carbon dioxide (CO2), so as decomposers break down the tissue, carbon dioxide is released into the atmosphere.
FOSSIL FUELS Oil, Gas, Coal are
examples. When these fuels are burned, they release carbon dioxide (CO2) and water (H2O) into the atmosphere.
Imbalance in Carbon - dioxide
QUIZ TIMEWhere all is Carbon present?What is CO2 or Carbon Cycle?How do plants and snimals have Carbon
in them?What factors are causing imbalances in
the Carbon Cycle?What can further imbalance in the
Carbon Cycle/ CO2 cycle lead to?What can we do to restore the balance of
the Carbon cycle?
