Ground-level ozone is a secondary pollutant formed by the reaction of nitrogen oxides and volatile organic compounds in the presence of sunlight, both of which are primarily emitted by fossil fuel combustion.

Phosphorus is a critical component of ATP, which is the primary energy carrier in cells, and it is essential for the process of photosynthesis in plants.

Chlorofluorocarbons (CFCs) were widely used as refrigerants, propellants, and foam-blowing agents before they were phased out due to their ozone-depleting properties.

Acidification of water bodies, often caused by acid rain, increases the solubility of aluminum, which is toxic to fish like brook trout by irritating their gills.

In the ocean, carbon dioxide dissolves in water to form carbonic acid, which then dissociates into bicarbonate and carbonate ions, with bicarbonate being the most abundant form.

Tropospheric ozone is a pollutant formed by the reaction of nitrogen oxides and carbon monoxide in the presence of sunlight.

Natural sources of carbon monoxide include volcanic eruptions, forest fires, and the oxidation of methane in the atmosphere.

The consumption of carbon dioxide by plants is influenced by various factors including the leaf boundary layer, stomatal conductance, and the energy balance (radiation exchange).

The air in our atmosphere is composed of molecules of different gases. The most common gases nitrogen  (78%), oxygen (about 21%), argon (almost 1%) and carbon dioxide (0.03%). Other molecules are present in  the atmosphere as well, but in very small quantities. Composition of air is measured in percent by volume,  at sea level at 15C and 101325 Pa.
