decomposers.....
Photosynthesis.
Animals emit carbon dioxide. Plants consume carbon dioxide.
consume both food and carbon dioxide
consume both food and carbon dioxide
Humans and most organisms like other mammals, reptiles, birds, insects, water animals convert the inhaled oxygen into carbon dioxide which is a waste gas excreted from the lungs.

No, Carbon Dioxide is not needed for all organisms because humans and most other animals consume oxygen not carbon dioxide. However plants use carbon dioxide during photosynthesis to create oxygen as a waste product. By the way you really need to check your spelling.
Carbon dioxide
No, organisms that use photosynthesis are called producers because they capture sunlight energy to convert water and carbon dioxide into glucose sugars, oxygen, and water. The glucose sugars are used by the plant to grow and reproduce. Since these plant organisms are creating biomass using sunlight, they are essentially producing food for other organisms to consume (who are called consumers).
The process whereby living organisms convert organic matter to carbon dioxide, releasing energy whilst consuming molecular oxygen.
Animals consume oxygen and release carbon dioxide. Plants consume carbon dioxide and release oxygen.

Yes, cellular metabolism converts glucose to carbon dioxide all the time, and this reaction is the source of chemical energy for all other chemical reactions in cells. It is the fundamental source of energy for most organisms (with hydro-thermal vent organisms being an exception).
Oxygen is by far the more plentiful. There is about 21% of oxygen in fresh air, but only 0.04 % of carbon dioxide.
