Dear All, I will be obliged to know the following. 1. Ratio of 'Oxygen liberated by a tree in daytime' to 'Oxygen absorbed by a tree at night'. 2. Ratio of 'Oxygen liberated by a tree in daytime in summer' to 'Oxygen liberated by a tree in daytime in rainy season' The figures may be approximate and I assure that the source will not be quoted anywhere. These simple queries have been raised repeatedly but every one refrains from answering. Pls provide, Regards
