Students tend to think that, because trace elements are required in tiny quantities, trace elements are not important. list two trace elements that the human body requires and briefly explain why each of those two trace elements is important and how have they been introduced into our diets?

These elements acts as catalyst for the various types of reactions that takes place in the body. Iron is taken in body by diet that we eat. It is found in green vegetables and acts as an important constituent of the hemoglobin which helps in the transport of oxygen.
