Step 1: Begin by understanding the four basic characteristics used to identify animals. Animals are heterotrophic, meaning they obtain their nutrition by consuming other organisms.
Step 2: Recognize that animals exhibit the ability to move at some stage of their life cycle, even if they are sessile as adults (e.g., sponges). Movement is a key characteristic.
Step 3: Note that animals are multicellular organisms, meaning they are composed of multiple cells that work together to perform various functions.
Step 4: Understand that animals do NOT have cell walls. This is a distinguishing feature that separates animals from plants, fungi, and some protists, which do have cell walls.
Step 5: Conclude that the presence of cell walls is NOT one of the four basic characteristics used to identify animals, as animals lack cell walls entirely.
