There must be genetic differences so the best fitted organisms will survive. If they were all the same then no one would be best fitted and Natural Selection wouldn't be able to occur
It's not 1 because a food shortage isn't required, there's always competition for food sources
It's not 2 because there doesn't need to be a change in the environment for natural selection, just for evolution.

What is a pathogenic microorganism?</h3>
An organism that can infect a host with sickness is known as a pathogenic organism.

In order to establish infections, virulence factors exacerbate the host's defense mechanisms. The pathogenicity of bacteria is determined by the nature and type of virulence factors.
