Cyanobacteria and heterotrophic bacteria have been clubbed together in Eubacteria of kingdom Monera as per the “Five Kingdom Classification” even though the two are vastly different from each other. Is this grouping of the two types of taxa in the same kingdom justified? If so, why?
Cyanobacteria synthesis their food and they are autotrophic. Heterotrophic bacteria depend on other organisms for their food. Both Cyanobacteria and heterotrophic bacteria are categorised under Eubacteria of kingdom Monera. Therefore the classification according to the cellular structure is justified.
