Answer 1

Both plants and animals use oxygen in the biological process of **cellular respiration**. This process allows them to convert glucose (and other nutrients) into adenosine triphosphate (ATP), which is the energy currency of the cell. In cellular respiration, oxygen is used to help break down glucose in the presence of oxygen, releasing energy, carbon dioxide, and water as byproducts. While plants also undergo photosynthesis, where they produce oxygen and glucose, they still rely on cellular respiration to utilize that glucose for energy, especially during the night when photosynthesis cannot occur.
