Hey Steve, not to get too picky, but there are very few aquatic plants 
which obtain CO2 from the sediment. These are Isoetes spp., Littorella 
uniflora, Lobelia dortmanna, Eriocaulon spp. Generally, this ability is 
restricted to small rosette plants growing in extremely oligotrophic 
waters. Other species, such as Valisneria spp., Heteranthera dubia 
and Myriophyllum spp. have been tested and found not to have the ability 
to extract CO2 from the sediment (Hydrobiologia 98:3 - 7, 1983).
