Here's why:

* Multicellular: Most fungi are multicellular, though some are single-celled (yeasts).

* Nucleated: Fungi are eukaryotic organisms, meaning they have a nucleus in their cells.

* Heterotrophs: They cannot produce their own food and must obtain it from other sources.

* Absorbing nutrients: Fungi digest their food externally by releasing enzymes and then absorbing the broken-down nutrients.
