Plants get carbon dioxide (CO2) from the atmosphere. This gas is a crucial component of photosynthesis, the process through which plants, algae, and some bacteria convert light energy into chemical energy, using sunlight to transform carbon dioxide and water into glucose and oxygen. All organisms, including plants, respire and produce carbon dioxide as a byproduct, creating a cycle where CO2 is used by plants and oxygen is released back into the atmosphere.
Plants need carbon dioxide in order to survive. Plants get this gas from
, which is something all organisms need.
