Astromaka and fried eggs in the gutter
By the mixing of two chemicals called 'bioluminescence'.
The green colored chemical that traps light is called Chlorophyll.
A firecracker gives off light because of a chemical reaction called combustion. Inside the firecracker, there are chemicals that burn when ignited, releasing energy in the form of light. The colors of the light produced depend on the specific chemicals used in the firecracker.
A glow stick produces light through a chemical reaction called chemiluminescence. This reaction occurs when two chemicals within the glow stick mix together inside the plastic casing. The mixing of these chemicals produces energy in the form of light.
Chemicals
The chemicals which are involved in a reaction are called Reagents or Reactants
There is a chemical in their bodies called luciferin. They mix it with several other chemicals and enzymes to create a reaction that puts out the yellow-green light you see.
The production of food from chemicals is called chemosynthesis.
When film is exposed to light, the chemicals on the film react to the light and create an image. This process is called photochemical reaction. The image is then developed and fixed onto the film, creating a photograph.
These chemicals are called reactants.
They are called decomposers
Electrons maybe?
