Detailed explanation-1: -Advertisement. Plant photosynthesis generates oxygen and carbohydrates in strict proportion, so we would run out of oxygen at the same time as we ran out of food. But we would reach lethal concentrations of carbon dioxide long before either of those things happened.
Detailed explanation-2: -Plants and animals would most likely perish. Photosynthesis emits considerable oxygen into the air; the atmosphere contains very little oxygen.
Detailed explanation-3: -The short answer is that plants use CO2 as part of the process of photosynthesis, and they do need a source of carbon dioxide in order to survive.
Detailed explanation-4: -Carbon dioxide, along with water, is one of the key ingredients that plants need to perform photosynthesis. With falling carbon dioxide levels, less photosynthesis will occur and some types of plant may die out altogether.
Detailed explanation-5: -One of the byproducts of respiration is CO2, this is the opposite of photosynthesis. It is not unusual for plants to stop taking in carbon dioxide to uptake small amounts of oxygen at night. In the event that plants cease to take up CO2 all together, they will cease to convert sunlight into carbohydrates, and die.
