Question

what is carbon and oxygen cycle?? what its causes??

Answer 1

Carbon and Oxygen

We usually refer to the cycling of carbon and oxygen in our atmosphere together because of how they are extremely interconnected.

 

With the exception of certain bacteria all animals, including aquatic, animals need oxygen to survive.

 

Even 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.

 

A cycle is a constant chain of events; there is no beginning and no end.

 

A Process is a series of steps involves in creating something.

 

The Carbon/Oxygen Cycle involves three major processes and one minor process: photosynthesis, respiration, combustion and decomposition.

 

Photosynthesis: 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. The chemical formula for photosynthesis is:

 

 

Plants take in                                                                 Plants give off

Carbon

dioxide

 

water

 

From leaves

 

Gives off

 

simple sugars    

 

 Oxygen

 

water

           CO2   +   H2O  +   Sun’s energy  +  chlorophyll                  C6H12O6  + O2  +   H2O        

 

 

 

 

Respiration:Animals  take in simple sugars and oxygen and release carbon dioxide, water and energy the chemical formula for respiration is:

 

Animals take in                                       Animals give off

 



releases

           C6H12O6   +     O2                             CO2        + H2O  +   energy

Carbon

dioxide

 

water

 

simple sugars    

 

 Oxygen

  

 

 

 

 


Combustion:This 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.

 

Decomposition: Is a minor part of the Carbon/Oxygen cycleDecomposition 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.For example:  When an animal dies all the carbon, oxygen, nitrogen, water, calcium etc. return to the soil and air during decomposition.Certain bacteria aid in the decomposition process.
