Decomosition reaction is single compound break into two or more simple substances under suitable conditions.
calcium carbonate is decomose by heating and form calcium oxide and carbon dioxide
CaCO3 -->  CaO + CO2       

displacement reaction in which a more reactive element displaces a less reactive element. 
 zinc react with hydrochloric acid and zinc displace the hydrogen and produce zinc chloride and hydrogen gas.
 Zn + 2HCl -->  ZnCl₂  + H₂

in chemical displacement reaction two compounds react to form two different compounds by interchanging the positive ions or on compound and element reacts in which a compound with higher reactivity displaces a compound with lower reactivity whereas in decomposition reaction one compound breaks to form two or more new compounds with different properties...
CaCO3----------------->CaO+CO2 this is an example of decomposition reaction
BaCl+CuSO4------------>BaSO4+CuCl2
Na+CuSO4----->NaSO4+Cu
