Heme is important to the function of hemoproteins which are involved in the generation of energy, detoxification of the host immune effectors among other processes.
The heme is an iron containing co-factor therefore lack of iron would mean there will be no heme, and thus lower amounts of functioning hemoproteins. Low amount of functioning hemaproteins means there will be lower energy yields.
The small number behind each element symbol designates the number of atoms of each element in a chemical formula. If there is no number, it is assumed there is only one of those elements. A large number in front of a compound designates how many units there are of that compound.

NITROGEN FIXING BACTERIA processes nitrogen in the atmosphere and make it available to other living forms in a usable form. Nitrogen fixing bacteria are micro organisms which are capable of transforming atmospheric nitrogen into fixed nitrogen.
