Combustion involves burning a substance in the presence of oxygen. It releases energy in the form of heat and light. Examples include burning of wood and fossil fuels.
In a decomposition reaction, a single compound breaks down into two or more simpler substances. An example is the electrolysis of water into hydrogen and oxygen.
Displacement reactions occur when an element replaces another in a compound. For instance, iron reacting with copper sulfate, replacing copper.
