Question

Carbon cycle in nature and how carbon is fixed on natire

Answer 1

There are only two processes through which carbon is fixed in nature or return back to atmosphere.:

• The utilisation of glucose to provide energy to living things involved the process of respiration in which oxygen may or may not be used to convert glucose back into carbon dioxide. This carbon dioxide then goes back into the atmosphere.

• Another process that adds to the carbon dioxide in the atmosphere is the process of combustion where fuels are burnt to provide energy for various needs like cooking, heating, transportation, etc.
