Sowbugs and pillbugs primarily feed on what?

Sowbugs and pillbugs are primarily detritivores, meaning they feed on decaying organic material. This includes decomposing leaves, dead plants, and other organic matter found in soil or along the forest floor. Their role is crucial in the ecosystem as they help recycle nutrients back into the soil, enhancing its quality and fertility. By breaking down this organic matter, they aid in the decomposition process, facilitating the availability of nutrients for plants and other organisms.

The other options do not reflect the primary feeding habits of these creatures. For example, fresh vegetables and household waste may not be their preferred food sources. Instead, sowbugs and pillbugs thrive on decomposed materials, which are rich in the nutrients they require for survival. Wood materials could be a part of their diet if they are decaying, but healthy wood is not a primary food source for them. Therefore, decaying organic material is the most accurate choice that describes their feeding behavior.
