Caption

In aquatic environments, plants fight for light and carbon to maintain photosynthetic activity. Since CO2 is often limited in freshwaters, many species have developed alternative carbon resources. Many plants have partial terrestrial life forms, such as floating leaves or above water growth, and thereby have access to atmospheric CO2. Others, like these green Stoneworts, are able to use bicarbonate HCO3- as a carbon-source.
