ECOSYSTEM THAT LIES
ALONG THE SHORELINE
BETWEEN THE FARTHEST
REACH OF THE HIGHEST TIDES
AND THE LOWEST REACH OF
THE LOWEST TIDE
TREE-DOMINATED
ECOSYSTEM IN TROPICAL
AND SUBTROPICAL LATITUDES
THAT CONSISTS OF GENTLY
SLOPING SANDY AND SILTY

SURFACE
• C) RESULTS IN AREAS OF HIGH PRIMARY PRODUCTIVITY AT THE
OCEAN SURFACE
• D) OCCURS WHERE WINDS BLOW AT RIGHT ANGLES TOWARD THE
COASTLINE

HYDROTHERMAL VENTS ________.
• A) CREATE OCEAN CURRENTS
• B) PROVIDE CHEMICALS TO SYMBIOTIC BACTERIA THAT SUPPORT
ECOSYSTEMS AT THE OCEAN FLOOR
• C) OCCUR IN TROPICAL AREAS AT THE OCEAN SURFACE
• D) MAKE THE PHOTIC ZONE OF OCEAN PELAGIC AREAS THE MOST
PRODUCTIVE
• E) ARE PASSAGEWAYS FOR FISH WITHIN CORAL REEFS
