An ecosystem is traditionally defined as a community of organisms functioning as an ecological unit in nature. Ecologists often study sites as far away from human influence as possible to get closer to nature.

We discuss the issue of energy nonconservation in the virialzation process of spherical collapse model with homogeneous dark energy. We propose an approximation scheme to find the virialization radius as well as modify a scheme recently proposed by Maor and Lahav. By comparing various schemes and estimating the parameter q, we conclude that the problem of energy conservation may have sizable ef...
