Answer:
Prokaryotes
Step-by-step explanation:
One of the kingdoms of nature is called Protist Kingdom, being characterized by the eukaryotic cellular organization, that is, with organized nucleus. Their representatives may be autotrophs, thus producing their food through photosynthesis, or even heterotrophs, which are those who do not photosynthesize. They may also be unicellular or multicellular, comprising, in their realm, beings such as protozoa, myxomycetes and algae. Protists are the simplest and most abundant form of life on earth today.
