Answer:
Protists
Explanation:
The kingdom that is being described is apparently a Protists Kingdom. This is a kingdom of only eukaryotic organisms, which are not animals, plants, or fungus. They are primarily microscopic and unicellular, or made up of a single cell but may include multicellular organisms as well. Also since they do not form natural groups or clades due to their exclusion of other eukaryotes.
