the process of respiration is essential in the oxygen/carbon dioxide cycle. respiration removes from the atmosphere and produces and releases to the atmosphere.

Respiration removes oxygen from the atmosphere and produces and releases carbon dioxide to the atmosphere

Explanation:

There are two types of respiration:

1.Aerobic respiration  

2.Anaerobic respiration

Aerobic respiration

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

Thus in aerobic respiration oxygen is taken and carbon dioxide is released.

Anaerobic Respiration

It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.  

Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
