The reason for recent increase in CO 2 concentration in the atmosphere. Introduction: CO 2 is a type of greenhouse gas that is dominant CO 2 gas is removed by the process of photosynthesis and stored in the form of carbohydrates. Its concentration is continuously exceeding in atmosphere along with other greenhouse gases.

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.
