Ecological Footprint of Humans 2:2

Question 1

How do the levels stay balanced as a constant percentage?

Answer 1

-In a balanced equation for photosynthesis and cellular respiration CO2 output is equivalent to the CO2 input required for photosynthesis.
-According to energy pyramids, there are far more producers than consumers—this accounts for the larger percentage of oxygen in the atmosphere.
-The oxygen input for cellular respiration is equivalent to the photosynthetic output of oxygen
-If the ratio of producers to consumers remains constant, then the atmospheric composition remains the same and balanced as it is now.
