In Biology (concerning macromolecules), a polymer can be broken down into simpler substances called monomers.
However, the general answerwould be a"chemical compound".
Two methods spring to mind. 1) Cracking, which may use heat, pressure and catalysts. 2) Digestion, which generally takes place in living organisms using enzymes.
The statement given is close to the definition of a "compound".
..... is a (pure, chemical) compound or substance
ZnCO3 ----> ZnO + CO2

Yes
A substance that can not be decomposed into simpler substance by a chemical or physical means is a chemical element.
A mixture can be defined as a material composed of two or more different substances that are not chemically combined. This makes nitrogen a pure substance.
It depends on the nature of the decomposition. if you are talking about biodegradeability in a substance, then no, its decomposition is mainly due to bacteria that will break down the various particles in the substance ("eat" them). There are, however certain chemical reactions which take place within the bacteria as the substance is being broken down, (much like those that happen in the human body) and the possibility of there being other products in the vicinity which may react to the substance (and degrade it) is always present. It could be said that decomposition is therefore a chemical reaction (or rather a series thereof), but with biodegradeability in mind it is not generally thought of as such.
If the above didn't answer your question, a substance that can be broken down into simpler substances is called a compound. Even the simplest compounds can be broken down into individual elements.
No. Elements cannot be broken down into simpler substances in a chemical reaction.

After a chemical reaction, some of the bonds have been broken, and some new bonds have been formed. So, that's how a substance is changed after the reaction.

An element is a pure substance that cannot be broken down into simpler substances by chemical means.
Its a decomposition reaction
A chemical element, by definition.
