The entire core of the Earth is mostly made up of iron. Plant life needs iron in their chlorophyll which takes part in the process of photosynthesis, and animal life needs iron within the hemoglobin molecules which helps distribute the flow of oxygen in blood to different tissue within an animal. Iron comes from the fusion of stars that have a large enough mass.
