Example of Explanation
Photosynthesis
Photosintesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the “fuel” used by all living things.
The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll
Most of trhe time, the photosynthesic process uses water and releases the oxygen that we absolutely must have to stay alive.
Oh yes, we need the food as well!
We can write the overall reaction of this process as :
6H₂O + 6CO₂ C₆H₁₂O₆ + 6O₂
