I don’t understand how 130kg can contain 145kg… Are there different laws for atmosphere weight compared to sea-level weight. Or are my numbers wrong?
In: Biology
Your numbers must be wrong. If I had to guess, you were using a chart of biomass for the wheat plant, which includes straw, seed that people harvest and make into bread, and roots, which stay in the soil.
From that perspective, it is sounds realistic that a certain number of wheat plants consumes 145kg of CO2 during their lifespans, and yields 130 KG of straw (plus roots and wheat). The root mass of most plants is approximately equal to above ground mass, and about half of the dry biomass comes from water (hydrogen incorporated into carbohydrates like cellulose), and half from air- plus a tiny amount from soil minerals.
