Describe the impact cellular respiration has on other organisms and the environment.

Cellular respiration is the process by which living organisms break down glucose in the presence of oxygen in order to produce energy, carbon dioxide and water is always given off as the by products of the reaction. The process of cellular respiration is very important for living organisms because it is the only way through which they can obtain the needed energy to fuel the life sustaining activities of their cells. The process of cellular respiration also has impact on the environment because the photosynthetic plants depend on the carbon dioxide and water, that is produced as the end product of cellular respiration to carry out photosynthesis. Animals in turn use the oxygen and glucose that is produce by photosynthesis to carry out the process of cellular respiration.

Respiration can be defined as the process by which an organism takes in oxygen and releases carbon dioxide, one in which the circulating medium of the organism (e. g., the blood) comes into contact with air or dissolved gases. Sometimes a distinction is made between external respiration, or an exchange of gases with the external environment, and internal respiration, an exchange of gases between the body's cells and the blood, in which the blood itself "bathes" the cells with oxygen and receives carbon dioxide to transfer to the environment.
