The environment may grow
What would most likely happen to the carbon dioxide-oxygen cycle if Earth's large forests were all cut down?
F There would be more carbon dioxide in the atmosphere because fewer plants would be using it to produce their own food. G The remaining plants would stop producing carbon dioxide, and animals would use less oxygen. H. The remaining plants would produce more oxygen, and animals would produce less carbon dioxide. J There would be more oxygen in the atmosphere because few plants would be using it to produce their own food.
F There would be more carbon dioxide in the atmosphere because fewer plants would be using it to produce their own food.
