What characteristic behavior do centipedes exhibit compared to millipedes?

Centipedes are primarily predators, which distinguishes them significantly from millipedes. This predatory nature means that centipedes hunt and feed on other small insects and arthropods, using their venomous jaws to subdue prey. In contrast, millipedes are mostly herbivores, feeding on decaying organic matter, leaves, and other plant materials. Their diet is essential for decomposing organic material in ecosystems, contributing to soil fertility. This clear behavioral and dietary distinction between centipedes and millipedes is fundamental in understanding their roles in ecological systems.

The other choices present misconceptions about these organisms. For example, centipedes are not social; they typically lead solitary lives, and millipedes do not have a strictly predatory role, as they mainly consume plant material. Additionally, while some species may have symbiotic relationships, it is not a defining characteristic for either group. Thus, the correct choice highlights the fundamental differences in diet and behavior between centipedes and millipedes, reinforcing the ecological roles each play.
