Calculate the density per cubic centimetre of bacteria

Assignment Help Biology
Reference no: EM132490072

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.

b) Calculate the density per cubic centimetre of Bacteria A on the agar plate if there are 1500 bacteria on a 100cm3 plate.

c) Assume the population of Bacteria B completely dies off. Bacteria A are now transferred to an open environment where they have lots of room for growth and a continual supply of food. Over the course of three days, the population of bacteria steadily increases as follows:

Day 1: 1500 bacteria

Day 2: 3000 bacteria

Day 3: 7000 bacteria

Day 4: 13,000 bacteria

Is this population of bacteria r-selected or k-selected? Explain how you arrived to your answer. Hint: review your definitions of "r" and "k."
