Answer to Question #175312 in Microbiology for Aliya

Question

1.     Bacteria A and Bacteria B are considered hardy bacteria and can survive in extreme environments when grown individually. However, when they are grown together in a closed environment (on an agar plate), Bacteria A thrives, while Bacteria B eventually dies off.

 

a)     Using your knowledge of competitive exclusion, explain what has happened. (2 marks)

 

Bacteria A and B are competition for the same limited resource on the agar plate, therefore both can’t live in the same place. So, one bacteria attacks the other until it dies.

 is this answer correct?

Answer 1

Answer

Bacteria A and B are competition for the same limited resource on the agar plate, therefore both can’t live in the same place. So, one bacteria attacks the other until it dies.

Basically the sated answer above is correct.

Competitive exclusion is where two individual or species compete for a limited resource in a particular ecological niche. One has to suppress the other in order for it to survive in a particular ecological niche. There Bacteria A took more advantage in order to suppress bacteria B for it to survive. So bacteria B had to die, in order for A to survive.
