After watching the above video, was wondering which hardwater plants, that evolved to utilize HCO3-, are being referred to. Does anyone have a list or examples? If so, would potassium bicarbonate be a source of carbon for these plants? Particularly interested in foreground plants that "switch"to bicarbonate when
I geeked out and came across some research papers that back up what the video above is taking about. These papers mention some Anacharis and Potamogeton crispus that can utilize bicarbonate. Curious if any foreground plants "switch" to bicarbonate.
The latter paper is where Potamogeton crispus is mention below figure 3.
I guess E viviparus uses bicarbonate?
