Question

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

Answer 1

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

Explanation; 
Respiration is one of the natural process that adds carbon dioxide to the atmosphere and at the same time remove or decrease the amount of oxygen. 
Both plants and animals use respiration process to generate energy in form of ATP that is needed for basic functions such a growth and movement. During this process, nutrients such as glucose are combined with oxygen to yield energy in form of ATP, and also water and carbon dioxide as by-products. 
Unlike photosynthesis, which uses carbon dioxide and water to yield nutrients (simple sugars) and oxygen gas, respiration uses oxygen and nutrients, to yield carbon dioxide and water, we can therefore they are antagonistic processes.

Answer 2

The process is photosynthesis wherein, respiration removes oxygen from the atmosphere and produces and releases carbon dioxide into the atmosphere. Respiration process plays a key role in the environment. The mitochondria in the cells of living organisms functions in the cellular respiration . The intake of oxygen by the organisms, convert it into carbon and is released in the environment, also know as Respiration Photosynthesis.
