UniversidadDeCádiz_GrupoB4B7_Entry4: Day 42

Hi everyone! We have observed both colums after other two weeks


The bottle that it has been kept by the dark has undergone few changes, only the level of the water has increased due to that the number of seaweed has increased too.



Also in the lit bottle the volume of water has increased, besides the water is murkier now, it is owing on to carbon dioxide. Green patch of cyanobacteria remains the same.


The same bottle, in the back where it has got no given it the light, behind the water it was returned darker because of reduced iron.


In addition, the sone of the iron colour has increased, it is due to oxidative iron bacterians.



The bottle ,which is at the left, is at the darkness. And the other bottle, which is at the right, is at the lit.


























The  bottle  which is at the lit.                                                           The bottle which is at the darkness


We can see in the comparative photograph:
