Question

The energy source to begin the photosynthetic process is oxygen sugar light energy complete darkness

Answer 1

Light energy is the energy source to begin the photosynthetic process.In this process light energy changed into chemical energy.In photosynthesis process light energy convert the water,minerals and CO2 into oxygen.And these compound change into energy rich compounds.photosynthesis process commonly present in green plants.

Light energy convert into chemical energy and this chemical energy stored in carbohydrates as sugar.This Sugar synthesized from water and carbon dioxide.

Photosynthesis process responsible for producing and maintaining the oxygen content of the Earth's atmosphere.

Two types of photosynthsis:-

1:-Oxygenic photosynthesis

2:-Anoxygenic photosynthsis

1:-Oxygenic photosynthesis:~

6CO2 + 12H2O + Light Energy → C6H12O6 + 6O2 + 6H2O

2:-Anoxygenic photosynthesis:~

CO2 + 2H2A + Light Energy → [CH2O] + 2A + H2O

So in both types of photosynthesis process we can easily say that if the sunlight are not available than photosynthesis process will not proceed.

So the light energy is the energy source to begin the photosynthesis process.
