During exercise, your body uses more oxygen to produce ATP for energy. This leads to a decrease in oxygen levels in the blood. As a byproduct of this increased oxygen consumption, carbon dioxide is produced and accumulates in the blood, leading to an increase in carbon dioxide levels.

Yes, an increase in carbon dioxide levels leads to a decrease in pH levels, as carbon dioxide reacts with water to form carbonic acid, which lowers the pH of the solution.
During respiration, oxygen is taken up by the body's cells and utilized in metabolic processes, leading to a decrease in oxygen levels in exhaled air. Meanwhile, carbon dioxide is produced as a waste product of these metabolic processes and is expelled from the body through exhalation, resulting in an increase in carbon dioxide levels in exhaled air.
Factors that can decrease the affinity of hemoglobin for oxygen include an increase in temperature, a decrease in pH (acidity), an increase in levels of carbon dioxide, and the presence of certain substances like 2,3-DPG.
The concentration of carbon dioxide in the air would increase if large trees were cut down. Trees help to absorb carbon dioxide during photosynthesis, so removing them would result in less carbon dioxide being removed from the atmosphere.
When the diaphragm inhales, oxygen is taken in and carbon dioxide is expelled. This process helps to increase oxygen levels in the blood and decrease carbon dioxide levels, ensuring that the body receives the oxygen it needs for cellular function.
