What organism uses carbon dioxide in the air?

Carbon Dioxide in necessary for photosynthesis as shown by the equation:
6CO2+ 6H2O---> C6H12O6+ 6O2 (aka) CO2+Water= Glucose and Oxygen

Therefore your answer will be either a plant or any eukaryote or prokaryote that performs photosynthesis. Some of these examples can be algae, ferns, or cyanobacteria. Any an organism which is a consumer (primary, secondary, or beyond) performs cellular respiration and instead releases CO2.
Hope this helps! :)

This is what i found on google “phytoplankton, tiny organisms that live in the ocean, are autotrophs. some types of bacteria are autotrophs. most autotrophs use a process called photosynthesis to make their food.” i hope this you for what your looking for
