C.
The organism is multicellular, has tissue organization, and has no cell wall.
D.
The organism is multicellular, lacks tissue organization, and consumes other organisms.

Answer 1

The characteristic that would indicate that the organism belongs in the kingdom Animalia is: The organism is multicellular, has tissue organization, and has no cell wall. Option C is the correct answer. This is because these characteristics are common to all animals and distinguish them from other kingdoms. Animals are multicellular organisms that lack cell walls, have tissue organization (including specialized cells that perform specific functions), and obtain nutrients by consuming other organisms. This is in contrast to other kingdoms, such as Plantae (which perform photosynthesis and have cell walls) and Fungi (which are multicellular but have no tissue organization and obtain nutrients by absorption).
