**6. Conclusion**

Biodegradation is a natural process executed by microbes. Among the microbes, fungi played vital role in the degradations of complex molecular substances into simpler ones. Here we have attempted to explore how fungi can solve the problem related to human and plant nutrition. Nutrition is a basic requirement of all living organisms. Fungi being heterotrophs act as scavengers utilize waste and bring nutritious food for humans as well as nutrients for the plants. Although many fungi are beneficial for humans and plants but there are notorious fungi which cause disease in human and plants that we have not touched upon.
