What fundamental characteristic defines the Kingdom Animalia placement of the Woodlouse Spider?
Answer
Multicellular and heterotrophic nature.
The classification into Kingdom Animalia establishes the most basic biological requirements for the organism. Being an animal means it must be multicellular, composed of many specialized cells working together, unlike single-celled Protista. Critically, it must be heterotrophic, meaning it obtains energy by consuming other organisms, which directly contrasts with the autotrophic nature of plants (Plantae) that produce their own food via photosynthesis. While segmentation is important, it is a feature refined at the Phylum level; the defining characteristic at the Kingdom level is this distinction from self-feeding organisms and non-cellular life forms.
