Answer:
because as bigger the concentration of carbon dioxide in blood is less oxygen present.
Explanation:
In human body the exchange among carbon dioxide and oxygen is constant, there need to be an equilibrium among them, if there is a considerable increase of carbon dioxide, that could be due:
1.- Because there is no enter of oxygen in the body.
2.- Suddenly there is an unusual production of carbon dioxide from the body.
In both cases this situation is not healthy for the body, so like a survival mechanism, the body will try to increase the ventilation rate to get more oxygen to the body.
