Question

Which cycle is the common biological method of carban fixation ?
(a) Gaseous cycle
(b) Calvin cycle
(c) Nitrogen cycle
(d) Hydrological cycle

Answer 1

Answer:

The correct option for the given question is option B Calvin cycle.

Explanation:

Carbon fixation is a biological process in which carbon is is fixed that is extracted from the carbon dioxide present in the atmosphere.

Calvin cycle is a part of photosynthesis is the major and common biological process that fixes carbon by carbon fixation method.

Answer 2

Calvin cycle is the common biological method of carbon fixation.

Option: (b)

Explanation:  

• In this cycle, carbon dioxide is used. Hence carbon fixation takes place. Hence it is common fixation method.  

• By this cycle carbon dioxide is converted into carbon. Then it is converted to bio molecules which are utilized by organisms.  

• Also it is takes place in C3 cycle of the plant photosynthesis. Carbon dioxide enters the leaves by small pores which is known as stomata.  

• The stomata is present in leaves upper surface in monocots and both in upper and lower surface in dicots.
