Answer 2

The essential and trace elements in the biological system are:

Essential elements - Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulphur, Sodium, Potassium, Magnesium, Chlorine, Calcium, etc.

Trace elements- Iron, Iodine, Zinc, Copper, Manganese, Cobalt, and Molybdenum.

Explanation:

• Essential elements are those which are very important and necessary for the processes of life.
• On the other hand, trace elements are also important but their requirement in the biological systems is quite low.
• The elements such as Carbon ($C$), Hydrogen ($H$), Nitrogen ($N$), and Oxygen ($O$) make up the biological system and are essential for it.
• Elements like Phosphorus ($P$), Sulphur ($S$), Sodium ($Na$), Potassium ($K$), Magnesium ($Mg$), Chlorine ($Cl$), Calcium ($Ca$), etc. are also required for several biological processes.
• Certain elements are called trace elements which include Iron ($Fe$), Iodine ($I$), Zinc ($Zn$), Copper ($Cu$), Manganese ($Mn$), Cobalt ($Co$), and Molybdenum ($Mo$).
