Which of the following substances is not involved in the chemical reaction that pro- duces smog? a. sunlight b. particulate matter c. automotive exhaust d. ozone

Particulate matter is not involved in the chemical reaction, which produces smog.  

•The air pollution, which diminishes visibility is smog.  

•The majority of the smog that one sees today is the photochemical smog.  

•It is generated when sunlight reacts with atleast one volatile compound and nitrogen oxides in the atmosphere.  

•The nitrogen oxides come from coal power plants, factory emissions, and car exhaust.  

•The volatile compounds are discharged from paints, gasoline, and many cleaning solvents. When sunlight react with these chemicals, they produce ground level ozone or smog and airborne particles.  

•The mixture of solid particles and liquid droplets found in the air is known as the particulate matter.  

•The particulate matter has no role in the production of smog.  

Thus, the correct answer is option b, that is, particulate matter.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
