Because it happens only when light present
The proper name for the light-independent reaction is the Calvin Cycle. It is also known as the dark reaction or the carbon fixation process because it does not directly require light to occur.

Calvin cycle or light independent reaction
The process is called photosynthesis. In photosynthesis, light energy is used by plants to convert carbon dioxide and water into glucose (energy) and oxygen.
The light reaction produces ATP and NADPH, which are needed to fuel the dark reaction. The dark reaction (Calvin Cycle) uses the ATP and NADPH produced in the light reaction to fuel the conversion of carbon dioxide into glucose. In essence, the light reaction provides the energy source that drives the dark reaction.
why light reaction of photosynthesis is essential before the dark reaction can procced?
A.T.P. and N.A.D.H are formed during light reaction.
There must be a light reaction first before dark reaction. This is so that there is something to be compared.
There is the light-dependent stage, where sunlight interacts with choloropyll to set up an electron-transport chain, then there is the chemical stage, where glucose molecules are synthesized from CO2 and H2O.
