Detailed explanation-1: -The answer is tiny organisms known as cyanobacteria, or blue-green algae. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen.
Detailed explanation-2: -Atmospheric oxygen comes mainly from green plants. When they’re exposed to light, green plants use carbon dioxide from the atmosphere to manufacture living matter and release oxygen into the air. This process is called photosynthesis.
Detailed explanation-3: -Scientists believe that the cow is the only animal that inhales and exhales oxygen, it added.
Detailed explanation-4: -During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration. Respiration is also the process by which once-living (organic) organisms are decomposed.
