Glucose is then USED by all organisms Glucose is then USED by all organisms (including plants) to make ENERGY(including plants) to make ENERGY

Sunlight energy is converted into Chemical Sunlight energy is converted into Chemical Energy (in the glucose)Energy (in the glucose)

Thus the sun provides the energy source for Thus the sun provides the energy source for life on earth, via the process of life on earth, via the process of photosynthesisphotosynthesis
