Helio Chemical ProcessConversion of Solar energy into chemical energy (bio energy) by a process called as

photosynthesis is calledis called as Helio Chemical Process

• Helio chemical process id a photosynthesis process which is the source of all fossil fuels and the food on which we live today.

• Bio mass and bio fuels are examples of Helio Chemical process.
