During nitrification, plants create nitrogen compounds nitrogen is added to the atmosphere bacteria break down amonia into nitrogen ammonia is changed back into nitrate

Option-(B,C,D): Excluding the first option the rest of the given options are all true.

Explanation:

During the nitrification process the amount of nitrogen present is changed back or converted into the nitrate form. And we can also say that the bacteria break down ammonia into nitrogen elements. And the total amount of nitrogen produced is released into the atmosphere.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
