Carbon and Oxygen
usually refer to the cycling of carbon and oxygen in our atmosphere
together because of how they are extremely interconnected.
the exception of certain bacteria all animals, including aquatic,
animals need oxygen to survive.
though our bodies are 80% water, Carbon is the most abundant
element our bodies.† It is carbon
that combines to produce sugars necessary for energy.
cycle is a constant chain of events; there is no beginning and no end.
Process is a series of steps involves in creating something.
Carbon/Oxygen Cycle involves three major processes and one
minor process: photosynthesis, respiration, combustion and
- †Green plants/trees take in Carbon
Dioxide and water using the chlorophyll in their leaves and energy from
the sun they release Oxygen, sugar and water vapor.
chemical formula for photosynthesis is:
Plants give off
+†† H2O† +††
Sunís energy† +† chlorophyll††††††††††††††††† C6H12O6† + O2† +†† H2O††††††††
- Animals† take in simple sugars and oxygen and
release carbon dioxide, water and energy
chemical formula for respiration is:
Animals give off
††††††††† C6H12O6†† +††††
O2†††† ††††††††††††††††††††††††CO2††††††† + H2O† +††
is the process of burning.† When
combustion occurs CO2 is released into the atmosphere.† Natural combustion includes volcanic
eruptions, however most pollution problems occur because cars and
factories release CO2 by their burning fossil fuels.
Is a minor part of the Carbon/Oxygen cycle
is when any organic matter (plants, animals) breaks down
chemically into all the simple elements that they are made of and
these elements return back to the environment.
example:† When an animal dies all
the carbon, oxygen, nitrogen, water, calcium etc. return to
the soil and air during decomposition.
bacteria aid in the decomposition process. (Decomposers).
