Millipedes are known to feed on what type of material?

Millipedes primarily feed on decaying organic matter, which is a crucial part of their ecological role. They are detritivores, meaning they help decompose dead plant material, fungi, and other organic debris. This feeding activity enriches the soil, promotes nutrient cycling, and aids in the breakdown of complex organic materials into simpler compounds that can be used by plants.

Their diet of decaying organic matter allows them to thrive in moist environments where leaf litter and other decomposing materials are abundant. This specific feeding behavior contrasts with the other options, which do not reflect the millipede's natural diet or ecological function. For example, while some organisms might consume fresh fruit or grains, millipedes are not equipped with the necessary adaptations to exploit those food sources. Furthermore, millipedes do not eat insects as part of their diet, as they do not hunt or scavenge on living or once-living animals. Instead, their role is to consume and recycle dead plant material, contributing to the health of their ecosystem.
