Answer:
well the otter needs O2 to breath and use the O2 to oxygenate his blood and etc. the CO2 is the dispelled gases and all used energy from the O2 and making the full Calvin cycle work? maybe idk
Otter has great effect on the concentration of carbondioxide and oxygen gas.
The relationship between CO2 and O2 for the otter is highly significant because otter affected the levels of both carbondioxide and oxygen gas in the atmosphere. Otter takes oxygen just like human through the process of breathing in order to breaking food molecules and releases carbondioxide gas.
While on the other hand, otter indirectly decreases the levels of carbondioxide gas by increasing the growth of kelp in water which absorb high amount of carbondioxide gas so we can say that otter has great effect on the concentration of carbondioxide and oxygen gas.
