Using the information you've calculated so far, determine the growth increment for the coming year for the UofL squirrel population. - 4.5 squirrels/yr Let's say that, after you calculated your predictions for unlimited growth of the UofL squirrel populations in the questions above, a bad storm comes through campus and wipes out half the trees! Now, the growth of the population of squirrels becomes limited. There are still 150 squirrels, but the…
