Organisms in the 6 kingdoms

Eubacteria

Salmonella enterica
E. Coli

Salmonella enterica and E. Coli are bacteria because these are organisms that are prokaryotes. The entire organism consists of a single cell with a simple internal structure.

Archaebacteria

Sulfolobus acidocaldarius
Thermoplasma volcanium

Sulfolobus acidocaldarius and Thermoplasma volcanium are organisms  that are also prokaryotes and also consist of a single cell with a simple internal structure but are very different from Eubacteria according to my science 11 biology teacher

Protista

Pediastrum boryanum
Plasmodium falciparum

Pediastrum boryanum and Plasmodium falciparum are protists because they are eukaryotic organisms that are not an animals, plants or fungus. The protists do not form a natural group.

Fungus

Hydnellum peckii
Clathrus ruber

Hydnellum peckii and Clathrus ruber are fungi because their means of reproduction involve producing spores and obtain nutrients through decomposing dead biological matter.

Plant

Drosera capensis
Cannabis sativa

Drosera capensis and Cannabis sativa are plants because, unlike fungi, they obtain nutrients through photosynthesis and rely on sunlight to survive

Animal

Synanceia
Tiliqua

These are animals because aside from their ability to move across terrain, air, or water, they obtain nutrients by consuming both living and dead organisms and they, unlike other kingdoms, use cellular respiration to breath
