The table below describes three different regions of an ocean ecosystem. Zone
Description
Zone 1 Air, sun, and water exposure; crashing waves.
Zone 2 Water depth less than 200 meters; lots of
sunlight; relatively warm water.
Zone 3 Very deep water; no light; cold except near the
thermal vents that emit heat and chemicals.
Based on table, which of the following is a valid conclusion?
A. There are no producers in Zone 3 that rely on photosynthesis.
B. Organisms in Zone 1 must be able to withstand very cold water.
C. Organisms in Zone 3 must be able to tolerate occasional air exposure
D. The warm water and abundant sunlight in Zone 2 limits the plankton population
