The quantity of phytoplankton (P) correlates with that of zooplankton (Z), as is expressed by the formula P=α Z<SUP>b</SUP>, where a and b are constants, and always positive. Therefore, there occurs no inverse correlation between the quantities of the two plankton populations, whereas formula N=Cr<SUP>-k</SUP> and P=C (1-γ) γ<SUP>-k</SUP> apply to plankton of similiar character distributed in a given area, where N is the total number of plankton individuals and γ=Z/N. Since if γ falls, the phytoplankton increase in number, the inverse relation is considered to hold, although actually the quantity of zooplankton either increases or, at least, remains unchanged.
