C) 35% of the forest in the bay area have ben lost. There areover 50 tree species and over 2700 plant species.

D) The functions of the forest are Protect hte quality of the water, improve quality of the air, and provide a habitate.

E) The types of trophs are autotrophs= plants or self feeders or heterotrophs= animals or other feeders.

F) If there was a loss of plankton there would not be enoughf food for the heterotrophs. An example is that it takes 8,000 lbs of plankton to = 1 lb of fish. To much plankton would block out to much sun light and the plants would die so there would not be enoughf oxygen.
