Answers
The natural things....
somethig brief...
You see, fireflies contain a chemical in their abdomen called luciferin. When that chemical combines with oxygen and with an enzyme called luciferase, the ensuing chemical reaction causes their abdomen to light up.
These all are the natural sources of the light and heat.
This is because we get the heat and light from the sun, fire, lightning as well as from the fireflies.
Explanation:
Sun is a huge source of heat and light.
From the fire also, that is due to the combustion of substances a lot amount of energy is released in the form of heat and light.
Lightning is a natural disaster, that also causes production of a huge amount of light and heat that is detrimental to the mankind.
Fireflies - The light produced by a firefly is due to a chemical reaction caused by an organic compound in their abdomens. The compound is called luciferin. As air rushes into a firefly's abdomen, it reacts with the luciferin. It causes a chemical reaction that gives the light and glow.
