During this process, leaves absorb sunlight and use it to transform carbon dioxide (CO\u2082) from the air and water (H\u2082O) from the roots into glucose (C\u2086H\u2081\u2082O\u2086), a form of stored energy. This energy fuels the plant\u2019s growth and development. As a byproduct, oxygen (O\u2082) is released into the atmosphere, making plants essential for maintaining the Earth\u2019s oxygen levels.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>Leaves play a crucial role in the survival of a plant and the balance of ecosystems.
