Carbon dioxide is one of the most important gases present in the atmosphere which constitutes of about 95 per cent of the the whole atmospheric gases.
Carbon dioxide is one of the main green house gases that helps in the absorbing heat from the atmosphere. It makes the temperature suitable for the organism to live on earth.

Answer:
because the body requires a higher supply of oxygen
Explanation:
Cellular respiration can be divided into two different metabolic processes: aerobic respiration which needs oxygen (O2) and anaerobic respiration (without O2). The aerobic cellular respiration is produced when glucose molecules react with O2 in order to form ATP, the energy currency of the cell. Aerobic cellular respiration is the main source for generating ATP. During exercise, the requirement of O2 will be higher because the cellular respiration rate is increased in order to produce more energy (ATP). In consequence, during physical activities, it is required have to breathe faster to supply this O2, which enters into the lungs to be transported to all the cells through blood circulation.
