During the day, trees in a forest undergo photosynthesis, where they take in carbon dioxide to produce oxygen and organic compounds. This process decreases the concentration of carbon dioxide in the air above the forest.
Actually carbon dioxide concentration increases at midnight and decreases at dawn At night the concentration is higher because plants take in oxygen and breathe out carbon dioxide at night so the concentration is higher. At dawn the concentration is lower because, plants breathe in oxygen at daytime and breathe out CO2 so the concentration is lower.
Lowest carbon dioxide content would be the vessel right after the lungs, pulmonary vein to the left atrium.
Oxygen levels are highest in the lungs (during inhalation) and lowest in the tissues (after oxygen is delivered). Carbon dioxide levels are highest in the tissues (after cellular respiration) and lowest in the lungs (during exhalation).
Solid carbon dioxide, also known as dry ice, has the lowest entropy among the different forms of carbon dioxide. In its solid state, the molecules are tightly packed together, resulting in a more ordered arrangement and therefore lower entropy compared to gaseous or liquid states.
July and August, when trees and vegetation are growing strongly in the northern hemisphere. This removes more carbon dioxide from the atmosphere.
The layer of the atmosphere that contains carbon dioxide and water vapor is the troposphere. It is the lowest layer of the atmosphere and where most weather events occur.

The troposphere contains the greatest concentration of the Earth's gases. It is the lowest layer of the atmosphere where weather occurs and where most of Earth's gases, such as nitrogen, oxygen, and carbon dioxide, are found.
The majority of Earth's carbon dioxide is found in the troposphere, which is the lowest layer of the atmosphere where weather occurs. This layer extends from the Earth's surface up to about 10-15 kilometers in altitude.
The lowest concentration of nitrogen can be found in the urine when it is first produced. As it accumulates in the bladder, so does the overall concentration of nitrogen.
