The question asks for a kingdom containing an organism that is eukaryotic, multi-cellular, and non-photosynthetic. Let’s examine the options based on these characteristics.
– Monera: Prokaryotic. Does not fit the ‘eukaryotic’ criterion.
– Protista: Eukaryotic, but mostly unicellular. While some multi-cellular forms exist (like some algae, which are photosynthetic) and some non-photosynthetic forms exist (like amoeba, which are unicellular), being *both* multi-cellular and non-photosynthetic is not a defining characteristic of the kingdom as a whole.
– Fungi: Eukaryotic (fits). Mostly multi-cellular (fits, except for yeasts). Non-photosynthetic (all are heterotrophic, so fits). Fungi contain organisms like mushrooms that are eukaryotic, multicellular, and non-photosynthetic.
– Animalia: Eukaryotic (fits). Multi-cellular (all are, fits perfectly). Non-photosynthetic (all are heterotrophic, fits perfectly). Animalia contain organisms like humans or insects that are eukaryotic, multicellular, and non-photosynthetic.
Both Fungi and Animalia fit the criteria of containing organisms that are eukaryotic, multicellular, and non-photosynthetic. However, all members of the Kingdom Animalia are multicellular, whereas the Kingdom Fungi includes unicellular organisms like yeasts. Given that all three criteria perfectly describe all members of the Kingdom Animalia, and multicellularity is not universal in Fungi, Animalia is a stronger fit as a kingdom primarily characterized by these features among the options, when compared to Fungi. The question asks in which kingdom *an organism* with these properties would be placed, and Animalia universally contains such organisms.
