water plants use co2 dessolved in water or they can use soluble co2.This we can prove by hydrilla funnel experiment
IN this experiment water pllant hydrilla absorbs dissolved co2 do the photosynthesis and release oxygen like normal plant, the resultant oxygen can be collected in a test tube

They do not live in the absense of CO2, Carbon Dioxide is present in water, they use it in the same way that land plants do.

There is carbon dioxide in the water. It's the CO2 that shelled animals and corals use to build CaCO3.

water plants are not in the absence of co2, What do you think the fish create? Water palnts make oxyfen release it just as it were above ground.

They extract their nutrition from the water and sunlight. Also, most water plants have some part or another above water. This is how they get their CO2. Algae, on the other hand, just survive on sunlight and water.
