Magnesium nitrate (MgNO3) is a nitrogen source. Magnesium sulfate (MgSO4) is a sulfur source.
The magnesium powder is used as a source of illumination for the photo. Just for the older cameras, the ones we have today use lights not the magnesium powder.
Not for humans (possibly for some plants).

When compounding magnesium and chlorine you get the compound, magnesium chloride, MgCl2, dissolved in seawater, is an abundant, natural source of the very useful metal magnesium. Magnesium is a common component of alloys. Alloys are produced by combining a pure metal with one or more other elements to form a new substance with desirable properties.
Magnesium nitrate (MgNO3) is a nitrogen source. Magnesium sulfate (MgSO4) is a sulfur source.
Monovalent sodium and pottasium ions and divalent magnesium and calcium ions are found in large proportions in biological fluids. These ions perform important biological functions such as maintainance of ion balance and nerve impulse conduction.

The Sun is the primary source of all biological energy. This biological energy is then transferred from one source to another through a variety of steps. Nature performs this transfer.
Origin? As in point of origin vs point of destiantion?
The word origin is a synonym for the noun source. The nouns origin and source are both abstract nouns.
In the product calcium is derived from calcium carbonate. Calcium carbonate is a natural source so if anyone of you is suffering from shellfish allergy, one may try this calcium carbonate.
