Detailed explanation-1: -A new study involving ANU and international collaborators has found plants release more carbon dioxide into the atmosphere through respiration than expected. Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration.

Detailed explanation-2: -A molecule of carbon dioxide (CO2) is made up of one carbon atom and two oxygen atoms.

Detailed explanation-3: -They absorb carbon dioxide from the air. This carbon makes up most of the building materials that plants use to build new leaves, stems, and roots. The oxygen used to build glucose molecules is also from carbon dioxide.

Detailed explanation-4: -Carbon is used by plants to build leaves and stems, which are then digested by animals and used for cellular growth. In the atmosphere, carbon is stored in the form of gases, such as carbon dioxide. It is also stored in oceans, captured by many types of marine organisms.
