Molybdenum is very important in the biochemistry of animals, plants, and microorganisms. It is the only element in the second transition series known to have natural biological functions. It occurs in more than 30 enzymes, in some of which it may be replaced by tungsten or vanadium. Tungsten is the only element in the third transition series known to have natural biological functions. Not only does it sometimes occur in enzymes that usually contain molybdenum, but there are some enzymes that are known only with tungsten. 

Soil microorganisms (fungi, bacteria and actinomycetes) play a major role in the degradation of organic matter, ultimately releasing nutrient elements— about 98% nitrogen, 5-60% phosphorus and 10-80% sulphur to the soil nutrient pool—along with micronutrients such as boron and molybdenum, into the soil for reuse by plants and animals. The role of biotic soils as sources of N and CH4... 

Trace elements, including potassium, magnesium, and iron, are required by microorganisms, while caldum, sodium, and silica may be necessary for the growth of some species. There may also be a requirement for traces of zinc, copper, cobalt, manganese, and molybdenum.
