What is the ecological advantage of the Yellow Bullhead processing substantial amounts of detritus?

Answer

It provides a food source nearly always present on the bottom

The ability of the Yellow Bullhead to utilize decaying matter, or detritus, as a significant portion of its nutritional intake provides a major ecological advantage. Detritus is organic breakdown material that settles on the substrate and is virtually guaranteed to be present in any natural water body, regardless of seasonal fluctuations in animal prey or vegetation availability. By efficiently scavenging these low-quality, yet constant, resources, the bullhead secures sustenance when higher-quality food sources are scarce, enabling population stability.
