A biologist observes an organism that is multicellular, has a cell wall made of chitin, lacks chlorophyll, and absorbs nutrients from dead organic matter. To which kingdom does this organism belong?

Fungi are multicellular organisms (mostly) with cell walls made of chitin, they lack chlorophyll and therefore cannot photosynthesize, and they obtain nutrients by absorbing them from dead or decaying organic matter (saprophytic nutrition). Plants have cellulose cell walls and contain chlorophyll, while Protista and Monera differ in cellular organization and other features.
