Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a soft gray Group 2 alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca2+ is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate.[5] Free calcium metal is too reactive to occur in nature. Calcium is produced in supernova nucleosynthesis.

Answer:
All living cells release energy from food molecules through cellular respiration and/or fermentation. Some cells make food molecules using light energy through the process of photosynthesis.
Two ways to cells get energy: cellular respiration and fermentation.
Fermentation: Fermentation, chemical process by which molecules such as glucose are broken down anaerobically.
Cellular respiration: Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
