Carbon dioxide is present in water from fish respiration and the breaking down of organics such as rotting leaves. As far as how they assimilate it, it's pretty much the same as terrestrial plants. Absorbsion through their leaves, roots, etc.
Carbon Dioxide is absorbed in the the water from the air and the plants absorb it from the water.
In the leaves and the roots there are special filtering systems that absorb the carbon-dioxide.
Plants breathe in carbon dioxide given off by aquatic animals:this carbon dioxide is further broken down into a form aquatic plants can use.
photophyis
yes
plants take in carbon dioxide for photosynthesis
As carbon dioxide. Plants convert carbon dioxide from the atmosphere and water to glucose (C6H12O6) and oxygen in the chemical process of photosynthesis.
plants take in carbon dioxide and release oxygen
Since carbon dioxide is present, the chloroplast will undergo photosynthesis. However, if carbon dioxide level is very low, C3 plants will end up using oxygen instead, which is called photorespiration.
Through pores in the green parts of plants (usually under leaves) called 'stomata'.
Carbon dioxide ;D and carbon dioxide leaves it. 8)
What
The stomata allows the carbon dioxide to enter.

stomata
Water, carbon dioxide and oxygen can enter a cell through the plasma membrane.
Through breathing.
