CREATOR, there is Light electro magnetic energy, that is what plant animal and human kingdom all need. Through the proces of Ionization.
Matter is slowded down (solidified) energy in the form of minerals.
Through a healthy biological soil life plants can pick up the inorganic minerals and it uses the phosphate to join carbon hydrogen and oxygen in order to form carbohydrates through the process of photosynthesis.
A plant has sap and humans have blood.
A plant builds its structure with cellulose and humans build bones out of plant food.
Water is used to form the carbohydrates that are in the plant using calcium as a catalytic base for the plant carbohydrates
So carbon is the element all biological life needs.Must be Calcium.
Are they the same needs? Hmmm a plant needs carbon dioxide and breathes out the oxygen, human needs oxygen in both forms through breathing in the air and by eating the complete complexed carbohydrates that in the process of digestion, friction and resistance between acids and the alkaline minerals releases their different electro magnetic energy and also in this way supplies the body with oxgygen.
I just read that one of the essential rules of physics and all biological life is: Anionic plant food makes growth, and cationic plantfood makes fruit.
Carbon is not anionic so the right answer must be calcium.
The rest of the explanation, I leave it up to you Moreless.
