Water comprises most of our mass too.
Carbon dioxide is one atom of carbon linked to two atoms of oxygen ("di-" means "two").
It is absorbed by plants and exhaled by animals.
I hope this helps. Thanks for asking.

Consider the molecular formula for glucose (other building blocks, such as other sugars, cellulose, and starches are similar ratios)
C<sub>6</sub>H<sub>12</sub>O<sub>6</sub>
Notice there are 6H<sub>2</sub>O, and 6C
The water is about 1.5 massive as C. So most of the mass comes from water. Other molecules in plants have a similar ratio.
