a.

Summary Introduction

To define:

What is the dividing line that lies between the macromolecules and the trace minerals according to the given graph?

Concept introduction:

The dietary minerals are of two types. Minerals that are needed in smaller amounts by the body is known as trace minerals. Some are iron, iodine, cobalt, copper, manganese, zinc, and fluoride. Minerals that are needed in larger amounts is known as macro minerals. Some macro minerals are calcium, phosphorous, sodium, chloride, magnesium, and sulfur.
