If you mean are Archaebacteria Heterotrophic, Autotrophic, or Saprophytic, they can be either heterotrophic or autotrophic
Amoebae are heterotrophic.
euglenoids
they are both
Proteobacteria are typically heterotrophic, meaning they obtain their energy by consuming organic compounds. However, some proteobacteria are also capable of being mixotrophic, meaning they can switch between autotrophic and heterotrophic modes of nutrition.
Archaebacteria can be autotrophic, obtaining energy through processes like photosynthesis or chemosynthesis, or heterotrophic, relying on organic compounds for energy. Some archaebacteria are also capable of surviving in extreme environments where other organisms cannot, often by utilizing unique metabolic pathways.
heterotroph
Eubacteria and archaebacteria can be both heterotrophic (obtaining nutrients from organic compounds) and autotrophic (able to produce their own food through photosynthesis or chemosynthesis), depending on the species.

Autotrophic archaebacteria, in the biological classification system, are members of the class halobacteria. Halobacteria live in salt water. Some species of halobacteria are: Halobacterium cutirubrum > Halobacterium salinarumHalobacterium denitrificans > Haloferax denitrificansHalobacterium distributum > Halorubrum distributumHalobacterium halobium > Halobacterium salinarumHeterotrophic archaebacteria are members of the class Methanobacteria. As their name suggests, these species metabolize methane gas to create energy. An example of this species is methanobacterium aarhusense.
Heterotrophic.
Amoebae are heterotrophic.
it is autotrophic nutrition
Heterotrophic
euglenoids
it is heterotrophic
Like all animals they are heterotrophic.
