A petri dish is inoculated with a single bacterium and the intrinsic rate of inc

Question

A petri dish is inoculated with a single bacterium and the intrinsic rate of increase for the species is 0.5. (Show work for all)

a. What will the size of the population be after 10 generations?

b. How often will the population double, if the rate of increase remains constant?

c. If the petri dish can hold one million bacteria, what will the rate of increase be after 25 generations?

d. The rate of resource use by the first species is 2 units/individual. A second species is added to the petri dish that uses resources at a rate of 3 units/individual and has a carrying capacity of 750,000. What will be the end result of adding in the second species of bacteria (i.e., will one species out-compete the other or will they co-exist)?
