Question: carbon dioxide is a limiting resource for most aquatic plants...
Carbon dioxide is a limiting resource for most aquatic plants, even though it can reach quite high concentrations in surface waters. How is that possible?
|Plants prefer to use bicarbonate for photosynthesis, so CO2 is not used.|
|b.||Plants deplete the water immediately surrounding their leaves, creating a low-CO2 boundary layer.|
|c.||Lakes and oceans are too acidic for most aquatic plants to function.|
|d.||It's bound up in bicarbonate, which plants cannot use.|
