For one Prey E/T = Ne1E1 – Cs1 / 1 + Ne1 H1 For two Prey E/T = (Ne1E1 – Cs1) + (Ne2E2 – Cs2) / 1+ Ne1 H1 + Ne2 H2 E = energy value often expressed as calories or joules / time N= abundance or sometimes biomass e = encounter frequency of predators and prey or how many prey a predator would encounter per unit time. Cs= cost of searching time H= handling time or the time from capture to the time of the next search,1 and 2 indicates
