They've gone up. They didn't have much choice, since before the Big Bang there was none at all.
Oxygen and carbon dioxide levels are maintained through the processes of photosynthesis and respiration in living organisms. During photosynthesis, plants and certain bacteria take in carbon dioxide and release oxygen, helping to increase oxygen levels and decrease carbon dioxide levels. Conversely, during respiration, organisms take in oxygen and release carbon dioxide, balancing the levels of both gases in the atmosphere.
Actually, the increase in greenery and oxygen levels is a result of photosynthesis, where plants use sunlight to convert carbon dioxide into oxygen. The greenhouse effect, on the other hand, refers to the trapping of heat in the Earth's atmosphere by greenhouse gases like carbon dioxide and methane.
The balance of oxygen and carbon dioxide is maintained in the atmosphere by the oxygen released by plant during photosynthesis and carbon dioxide released by human ,animal's etc in the atmosphere
Plants They take in carbon dioxide Then keep the carbon to grow and give out oxygen
From plant life. Animals including humans exhale carbon dioxide. Carbon dioxide is a heavy gas and fall to the ground. Whereupon it is absorbed by plant life. Under the process of photosynthesis, carbon dioxide in the plant is broken down into carbon and oxygen. The carbon is retained in the plant as biomass, and the oxygen is released back into the atmosphere, for animals to breathe. It is all part of the oxygen/carbon cycle.
Modern levels of carbon dioxide are significantly higher than when the first cells arose, while oxygen levels have decreased. The early Earth had higher levels of carbon dioxide and little to no oxygen, which eventually changed as photosynthetic organisms evolved and started producing oxygen through photosynthesis.
When the diaphragm inhales, oxygen is taken in and carbon dioxide is expelled. This process helps to increase oxygen levels in the blood and decrease carbon dioxide levels, ensuring that the body receives the oxygen it needs for cellular function.

Oxygen concentration tends to decrease as carbon dioxide levels increase. This is due to the fact that high carbon dioxide levels can displace oxygen in the air, leading to lower oxygen concentrations. Therefore, there is an inverse relationship between oxygen and carbon dioxide concentrations in the atmosphere.
The body can control breathing rate and depth to adjust oxygen and carbon dioxide levels. If oxygen levels are low, the body can increase breathing rate and depth to take in more oxygen. If carbon dioxide levels are high, the body can increase breathing rate to expel it. This is regulated by sensors in the brain that monitor oxygen and carbon dioxide levels in the blood.
During photosynthesis, plants remove carbon dioxide (CO2) from the environment and release oxygen (O2) as a byproduct. This process helps to reduce the levels of CO2 in the atmosphere and replenish oxygen levels.
well, you don't breath carbon dioxide, you breath oxygen
No, the amount of oxygen in the atmosphere is much greater than the amount of carbon dioxide. The current levels of carbon dioxide are approximately 0.04% of the atmosphere, while oxygen levels are around 21%.
Carbon Dioxide
Cellular respiration uses oxygen and generates carbon dioxide. Photosynthesis uses carbon dioxide and generates oxygen.
During exercise, your body uses more oxygen to produce ATP for energy. This leads to a decrease in oxygen levels in the blood. As a byproduct of this increased oxygen consumption, carbon dioxide is produced and accumulates in the blood, leading to an increase in carbon dioxide levels.
Algae play a critical role in maintaining carbon dioxide and oxygen levels through photosynthesis. During photosynthesis, algae convert carbon dioxide into oxygen, which helps balance the atmospheric oxygen levels. Algae also absorb carbon dioxide from the atmosphere, helping to mitigate excess carbon dioxide and reduce greenhouse gas emissions.
