Im guessing you were asking whether diffusion, osmosis or active transport is used for oxygen transportation in organisms.
Diffusion is the random movement of particles from an area with a high concentration to an area with a lower concentration.
So in humans for eample, gas exchange occurs in the lungs where there is a lower concentration of oxygen in the blood and a high conc of oxygen in the lungs. The oxygen then diffuses into the blood.
it gives us life to us and to all the living organisms
Cellular respiration is the process in which oxygen breaks down glucose to produce energy in the cells of living organisms.
Energy enters the ecosystem primarily from sunlight - which is used to power photosynthesis. Plants, in turn, become food for other living organisms such as bacteria, fungi, and animals. Once the energy is transferred from the sun to plants, it is mostly transferred between living organisms as "food". Some energy is also transferred from the sun to inorganic materials which are later taken up by living organisms for use in their metabolisms. An example would be the energy of the sun powering the weather that creates lightning, which converts some of the nitrogen of the atmosphere into nitrates which are absorbed by rain and deposited into the soil where they are absorbed by plants. Also energy is transferred from plants to oxygen consuming organisms when the plants produce oxygen through photosynthesis and then the oxygen is taken in by oxygen consuming organisms which use it in the oxidation of their food and expire carbon dioxide.
Plant organisms are used to common descent of all living organisms. This is to do research on human diseases.

In the cells of all living things, the power plant of the living organisms cells are mitochondria. The mitochondria take sugar (glucose) and oxygen and turns it into energy. I hope this helped!

The products of photosynthesis is used by organisms because they products are glucose and oxygen. Organisms use the oxygen in cellular respiration and the glucose is used for energy.
Cellular respiration is the process in which oxygen breaks down glucose to produce energy in the cells of living organisms.
Carbon is the most important atom in all living material. It combines with hydrogen, oxygen and nitrogen to produce proteins which are necessary to all living organisms. But of course living organisms need many other elements to form the many compounds necessary to sustain life.
Organisms which need oxygen are called aerobic organisms or aerobes. The oxygen is used in the process of respiration to release energy from food. Organisms which do not use oxygen in respiration are called anaerobic organisms or anaerobes. See: http://en.wikipedia.org/wiki/Aerobic_organism
