Accordingto Kenny, all living systems are open; theyare in continuous exchange of matter,energy, and information which results invarying degree of interaction with theenvironment from which the systemreceived input and gives back output in theform of matter, energy and information.
    • INPUTThe input can be matter, energy andinformation from the environment.THROUHPUTThe matter, energy and informationare continuously processed throughthe system which is also calledcomplex transformation known asthroughput.
