Detailed explanation-1: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Detailed explanation-2: -Plants, like animals, take in oxygen and give out carbon dioxide during respiration. Only during photosynthesis, plants take in carbon dioxide and release oxygen as a byproduct.

Detailed explanation-3: -Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.

Detailed explanation-4: -Final answer: Plants take carbon dioxide from the atmosphere mainly through their leaves.

Detailed explanation-5: -Plants use sunlight, carbon dioxide and water to make their food and this process is called photosynthesis.
