Question

The removal of carbon dioxide from the earth's atmosphere and the provision
of long term storage of carbon in the terrestrial biosphere is known
Options
(A) Carbon sequestration
(B) Carbon dating
(c) Carbon fixing
(D) Photosynthesis​

Answer 1

Explanation:

Carbon sequestration or carbon dioxide removal (CDR) is the long-term removal, capture or sequestration of carbon dioxide from the atmosphere to slow or reverse atmospheric CO2 pollution and to mitigate or reverse global warming.

Is it helpful..

Answer 2

(A) Carbon sequestration

• Carbon dioxide is the most commonly produced greenhouse gas.
• Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide.
• This is one way to reduce the amount of carbon dioxide in the atmosphere to reduce global climate change.

Explanation for incorrect :

(B) Carbon dating:Radiocarbon dating is a method for objectively estimating the age of carbonaceous material extracted from living organisms.

(c) Carbon fixing:Carbon fixation is the process by which plants fix atmospheric carbon to form organic compounds.”

All autotrophs, bacteria, algae and plants fix atmospheric carbon dioxide through the processes of photosynthesis or chemosynthesis.

(D) Photosynthesis:Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce oxygen and energy in the form of sugar.
