C02 + H20 = [CH20] + 02 follows in molar ratio the rule C02 Corg 02 = 1 1 1. The rate of atmospheric C02 sink under present biospheic conditions is 145 kgC per 1kg of chlorophyll. This level of sink is eventually the parameter that regulates the quality of life. 

7 BIOLOGICAL, CHEMICAL, AND PHYSICAL INDICATORS OF THE QUALITY OF BIOGEOCHEMICAL CYCLES 

Smeets and Weterings (1999) introduced four types of indicators. 

An important constituent of biogeochemical cycles is the water medium, by the state of which we can assess the level of change in the biogeochemical cycle of a certain element. The most widespread indicator of the quality of this constituent of 

Another indicator of the state of the ecosystem is the Simpson Index, N2 = [N(N — 1)]/[ ( — 1)]], where N is the total number of individuals of every species and n is the number of individuals of one species. In this case the equitability of abundance can then be derived by V = /Vi/jV2(mi, where Nlmax is N2 calculated for the same number of species and individuals, but equal abundances for each. Species abundances are more evenly distributed as V approaches 1.0 (Cox, 1985).
