Two mechanisms that affect the genetic diveristy of bacterial population

Horizontal gene transfer involves several mechanisms that can increase the genetic diversity of bacterial populations.

One of these mechanisms is bacterial conjugation in which a donor cell transfers genetic material to a recipient cell through a pili which function as a conduit.

Another mechanism of variability is through bacteriophages where genetic material is moved from one bacterium to another, this method is called transduction.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.
