Question
how are bacteria and fungi able to decompose the dead bodies of plants and animals and why are microorganisms considered as janitors of nature?

Answer
Dear Fifi,

Bacteria and Fungi have many different types of enzymes (functional proteins) that can break down dead, organic matter into its inorganic components.  

If it was not for bacteria and fungi's ability to decompose, we would all be up to our armpits in dead animals and plants.  So the decomposers (bacteria and fungi) truly can be considered "Nature's janitors."  They take solid matter and turn it back into gases and water that can be taken up by plants and turned back into live matter via photosynthesis and other chemical reactions.

Hope this helps.

I can answer biology-related questions in the areas of evolution, zoology, botany, genetics, and ecology. But I don't answer homework questions or provide ideas for your science fair projects. So students please do your learning the right way by reading your text assignments and studying!

Experience

At the University of Miami, I teach Evolution and Biodiversity, Botany, Zoology, Genetics, Ecology, and a variety of seminars (e.g., the Biology and Evolution of Human Gender Roles).

Education/Credentials
I have a B.S. in Biology and an A.B. in English from the University of Southern California (1980). I earned my Ph.D. in Biology in the area of evolutionary biology/visual physiology from the University of Miami in 1989.
