Whyphotosynthesis. os considered as the basic energy source for most living.world. give reasons. phase of photosynthesis as a light independent phase?

Answer 1

photosynthesis is considered as the basic source for the most living world as it is the reason for the formation of 99.99% food on this earth which is consumed by other organisms and survive.
Calvin cycle is the light independent phase of the photosynthesis

Answer 2

Photosynthesis is the most important natural process which sustains life on earth. It is the only known method by which oxygen is added to the atmosphere to compensate for oxygen being used in the process of respiration of organism and burning of organic fuels. Sinc, oxygen is also important in the efficient utilization and the complete breakdown of respiratory substrate and the formation of ozone in the stratosphere that filters out and stops harmful Ultraviolet radiations on earth it is clear that photosynthesis is the most basic energy source of the whole living world.

Biosynthetic phase (Dark or Blackman's Reaction) is the light independent phase reaction in which involves two categories: Calvin cycle (1955, Calvin and his colleagues) and C4-dicarboxylic acid pathway (Hatch Slack pathway,C4 pathway, 1965, 1967).
