In the communities found deep in the ocean off the shore of Japan, bacteria have special enzymes that allow them to form organic matter by chemosynthesis. These communities frequently have worms, clams, shrimp and many other organisms clustered together. These communities nestle around hydrothermal vents where superheated water, springs from the bottom of the ocean. In hydrothermal vent communities, we would not expect to find :
(a) carbon compounds
(b) chemosynthesis
(c) chlorophyll
(d) producers
