The 31 functional groups in the LAPE ecossystem model are grouped in the following categories (numbering is taken from the Ecopath model numbering):

Detritus is the ‘sink’ for all biomass from each group that is lost due to non-assimilation (faeces), or non-consumptive mortality (e.g. disease). Although detritus recycling is quite high within the zooplankton community and in benthic environments, it is for the most part simply lost from the pelagic system being considered in this model.
