There would be more carbon dioxide in the atmosphere because fewer plants would be using it to produce their own food.

Detailed explanation-1: -What would most likely happen to the carbon dioxide-oxygen cycle if Earth’s large forests were all cut down? There would be more carbon dioxide in the atmosphere because fewer plants would be using it to produce their own food.
Detailed explanation-2: -Answer and Explanation: Most, if not all, life on Earth would likely die if the carbon cycle stopped.
Detailed explanation-3: -Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles and pollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.
Detailed explanation-4: -If carbon dioxide is completely removed from a plant’s environment, we would expect the plant to stop producing high-energy sugars altogether. CO2 is necessary for the plant to perform photosynthesis, meaning without CO2 the plant has no way to obtain energy-it will likely die in this scenario.
Detailed explanation-5: -Plants take up carbon dioxide exhaled by animals and release oxygen inhaled by animals. Thus, forests maintain a balance between the two gases in atmosphere. Deforestation disturbs this balance and increases the amount of carbon dioxide in atmosphere.
