explain this "if we accept biochemical or molecular criteria for delineating species for this group then their diversity alone might Run into Millions" this line is written on NCERT page 260 chapter biodiversity and conservation

Dear student

Please refer the solution below for the said query

The given statement can be explained as:
The estimate of number of species present on earth is usually based on number of plants, animals, fungi.
There is no proper estimate of the number of species found in prokaryotic organisms as the conventional taxonomic methods have not been found suitable for identifying microbial species. Hence, if the study of chemical processes n them and molecular structure of these microbes is considered as criteria for describing and identifying them, then the number of species of these organisms will alone be in millions. 

Hope this information clears your doubt about the topic.
