Question

who found out that the glow-worms glow because of a chemical present in their bodies​

Answer 1

Answer:

1 : In glow-worms, a molecule called luciferin is combined with oxygen to create oxyluciferin. A chemical reaction with the light-emitting enzyme luciferase produces their illuminations. But glow-worms can't easily control the supply of oxygen, so they can't flash their lights on and off like some other firefly species.

2 : The cold light of the bioluminescent creatures results from the chemical process of luciferin, enzymes, and oxygen. In this case, the chemical energy rather than thermal energy excites the atoms into giving up photons.
