Explanation:
Detailed explanation-1: -So where does the mass come from? 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.
Detailed explanation-2: -Most of the mass of a plant actually comes from carbon dioxide that is used to make carbohydrates in the process of photosynthesis.
Detailed explanation-3: -A tree grows and increases mass through the chemical processes called photosynthesis. They obtain the majority of their dried weight from carbon dioxide in the air and nutrients from the soil and water as they grow.
