Carbon dioxide & oxygen balance

In summary, green plants perform photosynthesis during the day in the presence of sunlight and intake CO2 to produce O2. At night, they do respiration and intake O2 to produce CO2. However, even without animals, green plants would still survive because they are able to balance photosynthesis and respiration. The oxygen we use and the CO2 we release comes from this process. It is important to note that not all of the CO2 taken in during photosynthesis is given off during respiration, as the plant also uses some of it to build body structures. This process is known as carbon fixation.

Green Plants do Photosynthesis in day during presence of sunlight and intake C02 to produce O2.
In night, Plants do respiration and intake 02 to produce C02.
If there will be no animal then Green plants will survive ?
Because Earth is like ball, Plants will do photosynthesis=respiration (day=night) and produce oxygen=carbon dioxide.
Then from where the oxygen we use comes, and CO2 we release goes ?
I will be thankful to you if you answer me or find my mistake.

The amount of CO2 given off by the plant during cellular respiration does not equal the amount of O2 given off during photosynthesis. Only about 40% of the carbon dioxide taken in during the day is given off at night by the plant. The rest is turned into other organic compounds, such as cellulose, to build body structures. In other words, a lot of the carbon is used by the plant to grow larger.

Related to Carbon dioxide & oxygen balance

1. What is the carbon dioxide and oxygen balance?

The carbon dioxide and oxygen balance refers to the equilibrium between the amount of carbon dioxide produced and oxygen consumed in a particular environment. It is essential for sustaining life on Earth, as both carbon dioxide and oxygen play crucial roles in various biological and geological processes.

2. How is the carbon dioxide and oxygen balance maintained?

The carbon dioxide and oxygen balance is maintained through various natural processes, such as photosynthesis and respiration. Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into oxygen and glucose, while respiration is the process by which living organisms use oxygen to break down glucose and produce energy, releasing carbon dioxide as a byproduct.

3. What happens when there is an imbalance in carbon dioxide and oxygen levels?

An imbalance in carbon dioxide and oxygen levels can have significant impacts on the environment. For example, an increase in carbon dioxide levels can lead to global warming and climate change, while a decrease in oxygen levels can result in oxygen-deprived aquatic environments, also known as "dead zones."

4. How does human activity affect the carbon dioxide and oxygen balance?

Human activity, particularly the burning of fossil fuels, has greatly contributed to the increase in carbon dioxide levels in the atmosphere. Deforestation, which reduces the number of plants that can absorb carbon dioxide through photosynthesis, also plays a significant role. These activities have led to an imbalance in the carbon dioxide and oxygen levels, which has had severe consequences on the environment.

5. Can the carbon dioxide and oxygen balance be restored?

Yes, the carbon dioxide and oxygen balance can be restored through various means, such as reducing carbon emissions, promoting reforestation and afforestation, and using sustainable energy sources. It is vital for individuals and governments to take actions to restore and maintain a healthy balance of these gases for the well-being of our planet and all its inhabitants.
