Food from Light
Most of the energy used by living things
comes either directly or indirectly from
the sun. That’s because sunlight provides
the energy for photosynthesis. This is the
process in which plants and certain other
organisms synthesize glucose (C6H12O6).
The process uses carbon dioxide and water
and also produces oxygen. The overall
chemical equation for photosynthesis is:
6CO2 + 6H2O + Light Energy →
C6H12O6 + 6O2
Photosynthesis changes light energy to
chemical energy. The chemical energy is
stored in the bonds of glucose molecules.
Glucose, in turn, is used for energy by the
cells of almost all living things.
Photosynthetic organisms such as plants
make their own glucose. Other organisms
