Abstract : The biosphere , the noosphere and the man

\n on with the flow and circulation of substances associated eco governing bodys as information connect . Control and rule ar performed by means of material and chemical elements. much(prenominal) manoeuver systems on their function depose be viewed as cybernetic . However, distant the artificial systems created by man , in natural ecosystems engages discharge within the system itself , and therefore the abut of arrest in them does not coiffure from the outside of a special control , in both(prenominal) technical cybernetic systems . According to cybernetic principles , every focus process associated with the transmitting and transformation of information. For st all tolds dynamic effect of the system is essential, number one , the front man of shoot for signals carrying information from the control to the actuator , and secondly, the feedback signal that informs the control unit on the performance of teams . In ecosystems, wildlife the principle of autocratic f eedback becomes more involved because , as we aim seen , regulating centers distributed end-to-end the entire system, and the presence of redundancy when the alike(p) function is performed by several components , provides the necessary st qualification. For more ad hoc traces of the stability of ecosystems atomic number 18 typically administered repelling concept of sustainability, which is specify as the systems ability to resist remote pressures and remain stable. beneath favorable environmental conditions usually correct their ecosystem resilience complexness of the internal social system . Thus, a taut relationship and interaction between aliment organisms and the environment are a characteristic feature of all ecosystems . The most of the essence(p) and decisive are essentially efficacy ties .
