Most of it should be dead.
Some algae can increase their solutes and do fine at -2C etc in snow/
ice/arctic seawater etc. 
Most spores etc don't have to deal with more than maybe 3-4C. There are
exceptions, nothing that will grow in your tank though. 
There's photosynthesis going on under iced lakes, slower than summer etc,
but it still occurs.
Temp changes can signal a number of species shifts in various habitats,
marine systems are especially sensitive to smaller changes.

I don't think freezing a tank is really a good method:-)
