Plants require oxygen to breathe. In an atmosphere with carbon-dioxide only, they would suffocate.

How would the amount of carbon dioxide in the atmosphere change if their is no plants?

There would be significantly more CO2 in the atmosphere because plants take in CO2 during photosynthesis and fix the carbon into glucose.


Why is carbon dioxide present in the air?

Carbon dioxide is present in the air because plants need carbon dioxide to make food and without carbon dioxide plants would die and eventually the rest of the food chain.


If plants had no carbon dioxide?

The would not be able to photosynthesise


What happens if plants get too much carbon dioxide?

The plants would have a harder time growing. Carbon Dioxide is similar for plants as Oxygen is for people. However, plants can often adapt to changes in "air quality" much better then people can.


If you woke up tomorrow and all the plants on earth were gone what would happen to the amount of carbon dioxide in the air.?

we would all die because of all the carbon dioxide in the air and no plants and trees to take in the carbon dioxide to make oxygen


What will happen if the supply of carbon dioxide is permamently cut off?

Plants "breathe" carbon dioxide. They use it in photosynthesis. If carbon dioxide was completely wiped out, plants would die. During photosynthesis, plants turn carbon dioxide into oxygen, which we humans breathe. Once the plants die, humans would also die from lack of oxygen. Carbon dioxide is not something we should try to get rid of completely. The bulk of the carbon dioxide is created by nature. Man produces 3 to 6% of the CO2, the rest is natural.


Does warm carbon dioxide rise faster than cold carbon dioxide?

In an atmosphere of carbon dioxide, warm carbon dioxide would rise. Since carbon dioxide is better than twice as dense as air, it would need to be really hot before it would rise.


How would air composition change if there where no plant?

i think there would be less oxygen because the plants take in carbon dioxide and release oxygen


What cannot occur without carbon dioxide?

Photosynthesis in plants cannot occur without carbon dioxide, as it is a key component of the process. Without carbon dioxide, plants would not be able to produce glucose and oxygen through the photosynthesis process.


Why does a plant need carbon dioxide from the air to survive and carry out photosynthesis?

Plants need carbon dioxide from the air to survive and carry out photosynthesis because carbon dioxide is a key ingredient in the process of photosynthesis. During photosynthesis, plants use carbon dioxide along with water and sunlight to produce glucose, which is a form of energy that plants need to grow and survive. Without carbon dioxide, plants would not be able to make their own food and would not be able to survive.


How does cellular respiration effect carbon and oxygen in the atmosphere?

Cellular respiration uses oxygen and generates carbon dioxide. Photosynthesis uses carbon dioxide and generates oxygen.


Why do plants need to take in carbon dioxide for photosynthesis?

Plants need to take in carbon dioxide for photosynthesis because it is a key ingredient in the process of converting sunlight into energy. Carbon dioxide is used by plants to make glucose, which is their main source of food and energy. Without carbon dioxide, plants would not be able to produce the necessary sugars to survive and grow.
