Although organic detritus is an important energy source in marine ecosystems little quantitative data are available on rates of utilization by deposit feeders. A major reason is the difficulty of using isotope tracer techniques due to the release. and recycling of such non-conservative labels as carbon-14 from the detritus during suspension in an aquatic medium....
