Fig. 5. Changes in vertical distribution of elements of an ecosystem for 

 moments in time (t = 5 (1), 10 (2), 20 (3), 30 (4), 40 (5), and 60 (5) days) 

 vertical line shows depth, m. Horizontal dotted line shows upper boundary 

 of thermocline; n = nutrients, other symbols same as in Figure 4. Note 

 the difference in scales used for the different elements.
