We investigate the energy dependence of inelastic processes in systems whichpossess Efimov states. We consider the three-body recombination rate $K_3$where three free atoms interact to produce an atom--dimer pair, and therelaxation rate $K_{\rm rel}$ where an atom quenches a weakly bound state of adimer near an Efimov resonance to more deeply bound levels. Using a modelcapturing the key features of the Efimov problem, we identify new energyregimes for $K_3$, namely the NTR (Near Threshold Resonance) regime behavior$E^{-2}$ for negative scattering lengths and the NTS (Near ThresholdSuppression) regime behavior $E^2$ for positive scattering lengths. We alsoconfirm a previously found oscillatory behavior of $K_3$ at higher energy $E$.Finally, we find that $K_{\rm rel}$ behaves as $E^{-1}$ in the NTR regime.
