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: -When we breathe out, we release carbon dioxide into the air which is then used by the plants to make their food and the cycle starts all over again. This system is called the oxygen cycle.

Detailed explanation-4: -Plants, like animals, take in oxygen and give out carbon dioxide during respiration.

Detailed explanation-5: -(a) Correct answer: False. Explanation: During respiration, the plants take in oxygen and release carbon dioxide. This exchange of gases occurs through the stomata present on the leaves of the plant.
