If heat is required for a reaction to occur, it is an endothermic reaction. Endothermic reactions absorb heat from their surroundings in order to proceed.
exothermic reaction
Decomposition reaction: CaCO3(s) --(heat)--> CaOs + CO2(g)
Any reaction that consumes energy, or has a positive delta(H), is called an endothermic reaction.
The ability to produce heat and light in a chemical reaction is called combustion. It is a type of exothermic reaction where energy is released in the form of heat and light.
This is an exothermic reaction.

exothermic reaction
The type of reaction that involves oxygen and produces light and heat is a combustion reaction.
exothermic reaction. This type of reaction releases energy to the surroundings as heat.
Exothermic reaction gives free heat (energy).
