Step-by-step solution
The three-domain system proposed by Carl Woese divides Kingdom Monera into two domains on the basis of differences in 16S rRNA genes: Archaea and Bacteria. The third domain is Eukaryota which has all eukaryotes. Also, there are 6 kingdoms- Archaebacteria in domain Archaea, Eubacteria in domain Bacteria and Protista, Fungi, Plantae and Animalia in the domain Eukaryota. Methanococcus lies in Archaebacteria in domain Archaea and Rhizobium lies in Eubacteria in domain Bacteria.
