All sorts of microorganisms exhibit patterns that are very close to exponential population growth. For example, in the right hand graph of Figure 2 is a population of Paramecium growing in a laboratory culture. The pattern of growth is very close to the pattern of the exponential equation...
Enter a function into cell D2 that describes the increments you want on your graph. For example, if the function tracks periodic population growth in a culture, where "x" represents minutes, and you want to estimate the population every 20 minutes, type "=D1+20" without quotes into cell...
If the carrying capacity was 5000, the growth rate might vary something like that in the graph shown.Note that this is a linear equation with intercept at 0.1 and slope −0.15000−0.15000, so we could write an equation for this adjusted growth rate as:...
