Considering the amount of oxygen used for oxidation of detritus organic matter, oxycalorific co-efficient and morphometric feature (Area) of the zones as well as the energy consumed by the dominant detritivores, a method was proposed to estimate the detritus energy generation in aquatic habitats. The conversion of organic matter to energy by oxycalorific co-efficient was also counterchecked by the direct calorimetric energy estimates using Semi-Micro bomb-Calorimeter. The difference between direct estimate and estimate by oxycalorific co-efficient conversion was not statistically significant ("t" test, P > 0.05).
