Organisms use the oxygen they absorb from the air for their cells. The cells need this oxygen in order to carry out their functions.
name the organism which absorbs oxygen by diffusion
your lungs
Yes they do because they absorb oxygen while organisms that undergo photosynthesis absorb carbon dioxide.
All living organisms need water to survive, because they have cells. With air, not all living organisms need air. Some forms of bacteria do not need oxygen to live, and others can't stand oxygen.
The respiratory system seems like the obvious answer, but you used the word absorb. The respiratory system takes air into the lungs, but the red blood cells (erythrocytes) absorb the oxygen out of the air taken into the lungs. The circulatory system then delivers these red blood cells to the capillaries where the oxygen is traded for carbon dioxide as the cells need.
oxygen
Alligators are air breathers. They inhale and exhale through their nostrils. Their lungs absorb oxygen from the air that they inhale.
heat and air (oxygen, carbon dioxide)
Yes, most do. Trees, plants, they absorb the Co2 from the air and turn it into Oxygen.
From the air around it. During the day, plants absorb oxygen from the air. At night - they absorb carbon dioxide.
We exhale more oxygen than we use. Air contains approximately 20% Oxygen - when we breathe in - we absorb about 4% of the oxygen - and exhale the rest.
they absorb oxygen directly from the air without lungs.
