\subsubsection{Complexity in the Physico-chemical Subsystem}  At the Arctic Lake (Ar) variables related with light in surface, planktonic and benthic zones (SL, PL and BL) have high value of emergence. Variation of light was 10.28 $\pm$ 10.44. Meantime, benthic conductivity (BCd, 600.3 $\pm$ 40.8 µS) and percentage of water mixing between planktonic and benthonic zones (ZM, ) 50 $\pm$ 3.53%)  have very high self-organization. (Caution Remaining variables were classified in very high complexity category,  with the relative values exception  of variation !!!!) two variables associated conductivity (ICd=3896.96 $\pm$ 17.29 µS and BCd= 600,32 $\pm$ 40.53 µS) which were ranking in very low complexity category.  Remaining At the north highland lake (NH), light  variables were classified in increase their ranking to  very high complexity emergence  category,with the exception of two variables associated with inflow and benthic conductivity (ICd and BCd) that are ranking  in consequence its complexity was reduced to low and  very low categories. The ligh variation for all zones was between 12.31 $\pm$ 9.31. Meantime BCd (598.2 $\pm$ 95.91 µS) and Zm (62.05 $\pm$ 19.36) variables increase its  complexity to high  category. At the north highland lowland  lake (NH), light (NL), temperature  variables increase their ranking increases its level of change  to very high emergence category, in consequence its complexity high. The variation for all zones  was reduced between 11,3 $\pm$ 6,5. Also light variables (14.6 $\pm$ 7.4). Remaining variables had fair  tolow and  very low categories. BCd and Zm high emergence. Thus, self-organization, in general is low. As the result of the above facts,  variables increase its complexity to with very  high category. complexity were relating with hydrology (IO= 10.7 $\pm$ 6.5, RT= 61.9 $\pm$ 40.4) conductivity (ICd=870 $\pm$ 93.5, PCd=1132.6 $\pm$ 182.2) and pH in all zones of lake (7.0 14,6   7 $\pm$ 0.2)  At thenorth lowland lake (NL), temperature variables increases its level of change to very high. Also light variables. Remaining variables had fair to very high emergence. Thus, self-organization, in general is low. As the result of the above facts, variables with very high complexity were relating with hydrology (IO, RT) conductivity (ICd, PCd) and pH in all zones of lake.     At the  tropical lake (T), all physiochemical variables have similar levels of regularity (S) and change (E); consequently majority of o f  variables have high or very high complexity with the exception of ZM (16.48 $\pm$ 2.29)  and Sediment Oxygen (SdO2). (SdO2= 2 $\pm$ 0).  Based on PCA ordination of emergence, self-organization, complexity and autoposieis properties, we can summarize that variables of physiochemical subsystem can conform 3 groups. Group 1 including variables related with high changes or emergence as light. Group 2 conformed by variables associated with high regularity like conductivity and zone mixing, and Group 3 Variables expressing high complexity like temperatures, oxygen,pHs, retention time and inflow and outflow (Fig. **)
