No one should be exposed to secondhand marijuana smoke. Due to the risks it poses to lung health, the American Lung Association strongly cautions the public against smoking marijuana as well as tobacco products. More research is needed into the effects of marijuana on health, especially lung health. Updated March 23, 2015. See our public policy position on marijuana and lung health.
Carbon fixation is a biochemical process by which atmospheric carbon dioxide is incorporated by plants, algae and (cyanobacteria) into energy-rich organic molecules such as glucose, thus creating their own food by photosynthesis.arbon dioxide exists in the Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.
an organic compound is a compound which must contain hydrogen and carbon but carbon dioxide consists of carbon only so it is considered as a inorganic compound.hese compounds of carbon are just assumed to be inorganic. Also there is that one thing about carbon being covalently bonded with hydrogen in organic compounds. Due to that criteria carbon dioxide is considered inorganic. But actually there is no clear reason.
