The phenomenon that describes the movement of any kind of molecule from areas of higher concentration to areas of lower concentration is called diffusion.
This is the definition of an element.
Protein is the only nutrient broken down in the stomach. This is because only protease enzymes are present in the stomach acid.
A structural formula provides the most information because it shows not only which elements and how many atoms of them are present in the molecule, but it also shows how the atoms are arranged in the molecule.

If an unknown substance cannot be broken down into simpler substances it is made of one kind of atom and an element.

Sucrose is a type of carbohydrate. Pepsin is a protease, so it can only digest proteins, because enzymes are specific to one kind of molecule. Sucrose would be broken down by a carbohydrase.
The elements are things in their purest form whereas compounds are multiple elements combined together to form a compound. For instance, Carbon (C) is an elements whereas Carbon Dioxide (CO2, or Carbon + two Oxygens) is a compound.
A polymer molecule is a macromolecule.
