Water Flea F. E. Smith has studied population growth for the water flea. Let N denote the population size. In one experiment, Smith found that G, the rate of growth per day in the population, can be modeled by
a. Draw a graph of G versus N. Include values of N up to 350.
b. At what population level does the greatest rate of growth occur?
c. There are two values of N where G is zero. Find these values of N and explain what is occurring at these population levels.
d. What is the rate of population growth if the population size is 300? Explain what is happening to the population at this level.
