Question 4

A population of 10 yeast cells is put into a flask with growth media that contains all of the nutrients required for growth. The yeast has a doubling time of two hours; four hours after adding the yeast to the flask the population size is 40 cells. After three days the population size stabilizes at around 500 cells. Is this population exhibiting logistic or exponential growth? Explain your reasoning.

Accepted Answer

This population is exhibiting logistic g

B) was density-dependent. 
C) was density-independent. 
D) resulted in exponential growth for the bird population.
