Answer:
The natural method of removal of CO2 is
Photosynthesis by plants
Absorption of CO2 from the atmosphere by ocean water
Melting of glacial ice
Step-by-step explanation:
Respiration of living organism : In this process, Oxygen is consumed(removed) and Carbon dioxide(CO2 ) is formed.So it forms CO2 .
Photosynthesis by plants: Green plant containing. prepare their food in presence of sunlight by using CO2 , water ,Hence CO2 is removed from atmosphere.
Evaporation of ocean water : It increases the level of CO2 in atmosphere. The heating of oceans surface Degassed CO2 to atmosphere.
Absorption of CO2 from the atmosphere by ocean water : the plants under the oceans needs CO2 to carry out photosynthesis .Hence oceans absorbs CO2 from atmosphere .Here, CO2 is removed from atmosphere.
Melting of glacial ice : Glacial ice absorb carbon dioxide because it does not have organism respiration (organisms releasing CO2 ).They capture large amount of CO2 and called CO2 sinks.(Remove CO2)
