The majority of marine organisms are found in

• deep ocean waters

• shallow, coastal waters

• fisheries

• none of the above

Estuaries

• are always saltwater ecosystems

• are always freshwater ecosystems

• are ecosystems where both fresh water and salt water are present

• prevent the development of salt marshes

The arrangement of organisms in the open ocean is determined by the

• increase in salt content from shallow to deep waters

• size of the benthic zone, where photosynthesis occurs

• amount of nutrients and sunlight that are available

• distribution of zooplankton

Coral reefs are intricately shaped rocklike structures that are formed as a result of

• volcanic activity that is common in tropical marine environments

• the gradual accumulation and fusion of skeletons of bony fish

• the secretion of calcium carbonate by tiny marine animals

• minerals that are washed from land ecosystems and build up
