What do centipedes primarily feed on?

Centipedes primarily feed on live insects, making this the correct choice. As predatory arthropods, centipedes are known for their agility and venomous bites, which they use to subdue their prey. Their diet predominantly consists of insects and other small invertebrates, which they actively hunt and capture. This predatory behavior plays a crucial role in controlling pest populations, as centipedes help to maintain ecological balance by feeding on various insects that can be harmful to plants and crops.

In contrast, the other options do not accurately represent the feeding habits of centipedes. They do not consume plant matter or decaying wood, as their physiology and predatory nature are not suited for digesting plant material. Fungi also do not form part of their diet, as centipedes are not detritivores or decomposers. Instead, they thrive on a diet rich in protein that comes from living organisms, particularly other insects.
