2. Test: Add rabbits until the population is about twice as large as it was (200% of balance).
Click Play, and then Pause (1) after approximately ONE month. Next to each "Result" line
in the table, write "Increase" or "Decrease." Click Reset and then halve the rabbit population
(50% of balance). Record the results for this experiment in the table as well. 2 points
A. How did doubling the rabbit population affect the grass, snakes, and hawks at first?
B. How did halving the rabbit population affect the grass, snakes, and hawks at first?
