Sub Topic Name : The Carbon -Cycle |
Carbon is incorporated in life forms via photosynthesis, then converted to glucose and made into biologically important molecules which are further utilized and carbon dioxide is generated which goes back again to the atmosphere.
Presence of carbon dioxide in atmosphere.
All organisms are made up of carbon. But have you ever thought where in body is carbon present and how it comes inside the body?
Key Words | Definitions (pref. in our own words) |
---|---|
Presence of carbon | Found in the elemental form as diamond and graphite. Found as carbon dioxide, as carbonate and hydrogen-carbonate salts in various minerals, in life forms in form of carbohydrates, proteins, etc. the exoskeleton and endoskeleton of animals is also formed of carbonate salts. |
Photosynthesis | Process which incorporates carbon in life forms containing chlorophyll. Converts carbon dioxide from the atmosphere into glucose molecules which is used for synthesis of biologically important molecules. |
Combustion process | Another process which adds carbon dioxide in the atmosphere. Burning of fuels to provide energy for processes like heating, cooking, transportation etc. |
Increased percentage of carbon dioxide | The percentage of carbon dioxide in the atmosphere is doubled due to the industrial revolution. |

Encyclopedia and internet | Try to find about the global carbon prints and increasing carbon credits. |
Carbon is present in almost everything existing on the earth in some or the other form.
