    3 Consumption is the intake of food by a group over the time period considered. It is entered as the ratio of consumption over biomass (''Q/B''). Absolute consumption computed by Ecopath is a flow expressed, e.g., in t/km² /year, while the corresponding Q/B would be /year. Consumption over biomass is entered on the [[Basic input.htm|Basic input]] form.

    55There are various approaches for obtaining estimates of the consumption/ biomass ratio (''Q/B''). They may be split into (''i'') analytical methods and (ii) holistic methods: 
     
    3333This relationship can be used only for fish groups that use their caudal fin as the (main) organ of propulsion.
