Photosynthesis by land plants leads to the fixation each year of about 1 kg of carbon on
Fantastic news! We've Found the answer you've been seeking!
Question:
a. What volume of air (25°C, 1 bar) is needed to provide this 1 kg of carbon?
b. How much carbon is present in the entire atmosphere lying above each square meter of Earth’s surface? (Hint: Remember that atmospheric pressure is the consequence of the force exerted by all the air above the surface; 1 bar is equivalent to 1.020 × 104 kg m−2.)
c. At the current rate of utilization, how long would it take to use all the CO2 in the entire atmosphere above the forest? (This assumes that atmospheric circulation and replenishment from the oceans, rocks, combustion of fuels, respiration of animals, and decay of biological materials are cut off.)
