I believe oxygen, carbon dioxide, and nitrogen are all used by plants directly from the atmosphere.
Carbon Dioxide gas is taken in during photosynthesis and oxygen gas is given out whereas during respiration in plants oxygen gas is taken in and carbon dioxide gas is given out.
Oxygen is a product of photosynthesis that is used by plants and animals for respiration.
Oxygen!
Animals need oxygen to carry out life processes. Plants need carbon dioxide. Some animals and plants can use either if they need to.
The gas given off by photosynthesis is oxygen, plants take in carbon dioxide and generate it into oxygen.

CO2 (carbon dioxide) is exhaled by animals and needed by plants for photosynthesis.
Oxygen is a byproduct of photosynthesis
Oxygen is the gas that animals use in respiration. Plants use both oxygen and carbon dioxide. (This is assuming you mean cellular respiration.)
during photosynthesis plants take in carbon dioxide and give out oxygen
oxygen
Oxygen is the waste product of plants that animals need in the process of oxidative phosphorilation.
Definitely Carbon Dioxide.
Carbon Dioxide gas is taken in during photosynthesis and oxygen gas is given out whereas during respiration in plants oxygen gas is taken in and carbon dioxide gas is given out.
