Which mineral is a macromineral?

Explanation:
Macrominerals are minerals the body needs in relatively large amounts each day. Calcium is a classic macromineral because the body requires a substantial daily intake, around 1000 mg for adults, to build and maintain bones and teeth and to support functions like muscle contraction and nerve signaling. The other minerals listed are trace minerals, needed in much smaller amounts: iron for oxygen transport in blood, copper for enzyme activity and iron metabolism, and fluoride mainly for dental health in small amounts. So calcium fits the category of the macromineral.
