The experimental proof was provided by Ruben Hassid and Kamen who used water containing heavy isotope of oxygen ie O18 and carbon dioxide containing normal oxygen in the process of photosynthesisThe oxygen released in the. Carbon monoxide is a linear molecule but the electronegativity difference between carbon and oxygen is significant enough to make the. Is Co2 Polar Or Nonpolar Youtube Nope all the O2 is formed during the first stage of photosynthesis from water. . It can be easily checked by isotopic analysis. Plants and other photoautotrophs use solar energy to produce carbohydrate from atmospheric carbon dioxide and water by photosynthesis. Mangroves are among the most carbon-rich biomes containing an average of 937 tC ha-1 facilitating the accumulation of fine particles and fostering rapid rates of sediment accretion 5 mm. The latter is used in packed-bed columns downstream of non-GAC filtration or membrane processes
