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

Which of the following is not characteristic of salt marshes and mangrove swamps?

• Both provide habitats for wildlife

• Both are dominated by marsh grasses

• Both are found along coastal areas

• Both are threatened by development

Which of the following is a threat to coral reefs?

• oil spills

• sewage

• pesticides

• all of the above

Why doesn’t photosynthesis occur in deep ocean water?

• The water temperature is too cold

• There is no sunlight

• There are not enough nutrients

• The salinity level of the water is too high
