b. Wetlands protect and improve water quality, help control erosion and flooding, and provide habitat for terrestrial and aquatic life.
| OK |
c. The percentage loss of Forest in the Bay area is 35%. There are more than 2,700 plant species and more than 50 major tree species in the Bay area.
| OK |
d. Forests protect water quality, create habitat for fish and wildlife, improve air quality, encourage recreation, and contribute to the economy.

e. Autotrophs = producers; self-feeders; primary food producers; plants and algae Heterotrophs = consumers; other-feeders; animals or organisms that eat plants Saprotrophs = decomposers; digest the bodies of both plants and animals and the waste products of both.
| OK |
f. Since the plankton serve as the base of the food chain, if there were no plankton then there would be no system. If there were too many plankton then they would deprive the other organisms of resources and the system would not be able to function correctly.
