Hint: Kingdom which contains oldest, most abundant, prokaryotic unicellular organisms. These organisms are the most numerous and widespread organisms on earth.

Complete answer:
Monera are the most primitive, unicellular, prokaryotic organisms and because of their simple structure they show nutritional diversity as given below:-
Autotrophs-
-The autotrophic bacteria either use chemicals as a source energy that is chemoautotrophic or are photosynthetic that is photoautotrophs.
-Example- Anabaena, spirulina, cyanobacteria.
Parasite-
-Some organisms are parasites which live off a living host like Leucothrix mucor.
-Example- Bacillus, Diplococcus pneumoniae, Mycobacterium tuberculosis.
Saprobes-
-Some organisms are saprobes, feeding off dead organisms and waste that is decomposers.
-For example, the bacteria that feeds on sweat on our skin are saprobes.

Additional Information: -The taxon monera was first proposed by Ernst Haeckel and later the taxon was raised to the rank of the kingdom.
-Monera divided into three
Archaebacteria
Eubacteria
Mycoplasma
-Mode of reproduction is by binary fission that is simplest form of asexual reproduction by just one parent.
-Cyanobacteria produce food and oxygen for aquatic life.
-Archaebacteria shows different types of habitat like some lives in saltwater, in acid, deep in the oceans, at temperature above 100 degree, in muddy swamps, in the intestines of cattles and even on human beings.

So, the correct answer is,’Monera.’

Note: -Based on the shape of organism they are further sub- divided into:
Vibrio- comma shaped bacteria
Bacteria- rod shaped bacterium
Bacillus- rod shaped and spore bearing bacteria
Spirochaetes- thin spiral shaped bacterium
Spirillum- spiral shaped bacterium
