DENDROLOGY

Detailed explanation-1: -When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out).

Detailed explanation-2: -The average human exhales about 2.3 pounds of carbon dioxide on an average day. (The exact quantity depends on your activity level-a person engaged in vigorous exercise produces up to eight times as much CO2 as his sedentary brethren.)

Detailed explanation-3: -When carbon dioxide reacts with water, carbonic acid is formed, from which hydrogen ions dissociate, increasing the acidity of the system. Therefore, in addition to any greenhouse effect, anthropogenic carbon dioxide emissions to the atmosphere can increase the acidity of the atmosphere and precipitation.

Detailed explanation-4: -Overview. Cellular respiration is the process in which the cells of all living things break down the organic compound glucose with oxygen to produce carbon dioxide and water. Oxygen is brought into the body with each inhalation, and carbon dioxide is released with each exhalation.
