Answer 1

In nature, during a 24-hour period, green plants continuously require and use both carbon dioxide and oxygen.

During the day, plants use carbon dioxide for photosynthesis to produce glucose and oxygen. At night, while photosynthesis ceases, plants continue to respire, consuming oxygen and releasing carbon dioxide. Therefore, the correct answer is a both carbon dioxide and oxygen.
