11. Virginia's Great Dismal Swamp is largely a red maple forest. Previously, there were more bald cypress and
white cedar trees in the area. Tree cutting, extensive draining, and the prevention of natural forest fires have
changed the balance of tree species. The balance has shifted because these actions have-
a. preserved the amount of soil in the swamp.
b. increased the rate of cellular respiration in cedar.
C. altered the pattern of succession in the swamp.
d. decreased the amount of sunlight needed by cypress.
