The pattern of change in CO₂ concentration is new plant growth in the spring increases photosynthesis rates, which lowers CO2 concentrations; this decline continues until autumn, when leaves fall and decompose, raising CO2 concentrations.
The level of carbon dioxide within the surroundings rises and falls every 12 months as plant life, thru photosynthesis and respiration, absorbs the gas in the spring and summer season, and launches it in fall and wintry weather. Now the range of that cycle is expanding as extra carbon dioxide is emitted from burning fossil fuels and different human activities.
In spring, flora in the Northern Hemisphere starts to develop and absorb CO2 from the atmosphere, so atmospheric CO2 attention decreases as the road dives down. In fall, flora starts to decay and release their CO2 again into the ecosystem, so atmospheric CO2 attention increases the line shoots up. plants are accumulating carbon within the spring and summer while they are lively, and they're liberating carbon again to the air in the fall and winter.

Answer:
<em>The correct option is A) they are all classified as pure substances.</em>
Explanation:
Pure air is a term which is used to described air which is free from pollutants or other contaminants. All the substance from which air is made are considered as pure substances. Hence, option A is correct.
Other options, like option C, is false because the components of the air are no chemically bonded to one another. They exist freely. Options D is false because not all the components of air can be classified as an element. For example, carbon dioxide is not an element.
