They make magnesium oxide, MgO.
Oxgyen is needed for aerobic respiration, which gives out energy.

No, it is an element.
To make magnesium oxide, one can heat magnesium metal in the presence of oxygen. This process, called thermal decomposition, causes the magnesium to react with oxygen and form magnesium oxide.
It makes magnesium sulphate, and copper.
When magnesium reacts with sulfur, they form magnesium sulfide with the chemical formula MgS. This compound is a binary ionic compound made of positively charged magnesium ions and negatively charged sulfide ions.
