We compare two selection procedures in a numerical method proposed for the numerical simulation of the long time behaviour of solutions for a size-structured population model whose dependency on the environment is managed by the evolution of a vital resource and with a free sign growth rate. We obtain the approximation of singular asymptotic states such as stable steady ones and attractive limit cycles.
