Plants need carbon dioxide to preform photosynthesis.
Carbon Dioxide dissolves in ocean water. Plants in the ocean use the carbon dioxide dissolved in the ocean water.
decomposition
Photosynthetic organisms counter the greenhouse effect. This is because plants use carbon dioxide and turns it into oxygen instead. Carbon dioxide is causing the greenhouse effect.
No, Carbon Dioxide is not needed for all organisms because humans and most other animals consume oxygen not carbon dioxide. However plants use carbon dioxide during photosynthesis to create oxygen as a waste product. By the way you really need to check your spelling.
Autotrophs
Photosynthesis.

Carbon dioxide is dissolved into the sea. Marine organisms use the dissolved carbon dioxide to make shells of calcium carbonate. When these organisms die, they fall to the sea bed. Layers of dead organisms and sediment build up on the sea bed. These layers are compacted and compressed to form sedimentry rock.
Autotrophs are organisms that can synthesize their own food. They will use the carbon dioxide in the process of photosynthesis.
Respiration.
Plants, use carbon dioxide (CO2) water (H2O) and sunlight to make energy (photosynthesis).
Well I use carbon dioxide in my fire extinguisher. What do you use carbon dioxide, or to put it another way? In what do you use carbon dioxide? Humans breathe out carbon dioxide... Breathing it out is not exactly using it. That would be more like making it.
