Question

in which process co2 is released ?

Answer 1

Processes or regions that predominately produce atmospheric carbon dioxide are called sources. Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

Respiration and Decomposition

You are probably familiar with respiration and the respiratory system. One definition of respiration is the exchange of oxygen and carbon dioxide between the blood of an animal and the environment. Carbon dioxide is also released when organisms breathe.

Respiration also takes place at the cellular level. All plants and animals return both carbon dioxide and water vapor to the atmosphere. Every cell needs to respire to produce the energy it needs. This process is known as cellular respiration. The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide isC6H12O6 + 6O2 → 6CO2 + H2O + energy

 glucose + oxygen → carbon dioxide + water + energy

 

Respiration is also the process by which once-living (organic) organisms are decomposed. When organisms die, they are decomposed by bacteria. Carbon dioxide is released into the atmosphere or water during the decomposition process. released into the atmosphere during the process of cellular respiration.
