The dynamics of entanglement and the phenomenon of entanglement sudden death (ESD) [T. Yu, J.H. Eberly, Opt. Commun. 264 (2006) 393] are discussed in bipartite systems, measured by Wootters concurrence. Our calculation shows that ESD appears whenever the system is open or closed and is dependent on the initial condition. The relation of the evolution of entanglement and energy transfer between the system and its surroundings is also studied.
