Exhaled breath contains:
There's a process called gas exchange which takes place in the lungs: put simply, both oxygen & carbon dioxide are transported around the body in the blood stream; when the blood reaches the lungs it does a trade - swapping waste CO2 (a by-product of the cellular respiration which is constantly going on in every cell in your body) for oxygen in the air you've just breathed in. So the air you breathe out contains that waste gas, plus the proportion of CO2 that was already in your last breath in.
The source of carbon in glucose resulting from photosynthesis is carbon dioxide (CO2) taken in from the atmosphere. During the process of photosynthesis, plants use sunlight to convert water and carbon dioxide into glucose and oxygen. The carbon atoms in glucose come from the carbon dioxide molecules that plants absorb.
carbon dioxide + water --------> glucose + oxygen.
The reactants in photosynthesis are carbon dioxide and water. The overall reaction of photosynthesis is: carbon dioxide + water --> glucose + oxygen gas + water (some diagrams include the energy provided by light, but this is not a true reactant) The catalyst, which is mostly recycled, is chlorophyll.
6H20 + 6CO2 + Light Energy -----------> C6H12O6 + 602 Water + Carbon Dioxide + Light Energy --------> Glucose + Oxygen Photosynthesis takes place in the plant cell's chloroplasts.

Trace amounts of water vapour are also exhaled, alongside the carbon dioxide.

H2O
Yes, when you exhale, you release carbon dioxide that was produced during the process of cellular respiration in your body. This exchange of gases helps maintain the balance of oxygen and carbon dioxide levels in your bloodstream.
Oxygen
Carbon plus oxygen equals carbon dioxide. When carbon undergoes combustion or oxidation, it combines with oxygen to form carbon dioxide, releasing energy in the process.

The amount of carbon dioxide emitted by an individual is a significant part of their carbon footprint. This includes emissions from activities like transportation, energy use, and food consumption. Reducing these emissions can help decrease a person's overall carbon footprint.
Either CO2, carbon dioxide or CO, carbon monoxide
Plants use the carbon dioxide to make food.
