What components contributes to the mass of a photosynthetic organism

The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water

Photosynthetic organisms use carbon to generate organic molecules and build biological mass. The oxygen produced as a bi-product of photosynthesis is used by many organisms, including plants and animals, for cellular respiration
