A newly discovered single-celled eukaryotic organism is observed to obtain nutrients by engulfing smaller food particles. Based on the classification presented in the text, to which group would this organism most likely belong?
Explanation
The text describes Protists as 'mostly unicellular eukaryotes' and states that 'The three kingdoms are distinguished partly by their modes of nutrition: Plants produce their own sugars... Fungi... absorb nutrients... Animalia... ingest other organisms.' While Animalia also ingest, they are multicellular. The described organism is unicellular and eukaryotic, and obtains nutrients by engulfing, which aligns perfectly with the characteristics of many protists.
