This answer would be FALSE! Smog is a combination of two things: 1. an emission of something that will cause a haze (i.e. burning of fuel-coal, etc...) and 2. natural fog.
If the two combine, then we will get smog. Therefore, if we cut down on our fuel burning and pollutants within the environment, we could also cut down on smog.
In Biology you study living organisms, so that would include plants and animals.
