Where are coral reefs found?

• Polar waters

• temperate, mid-latitude waters

• tropical waters

• only near volcanos

Which of the following is not an environmental function of wetlands?

• increasing runoff

• absorbing and removing pollutants from water

• trapping carbon that would otherwise be released into the air

• controlling floods

Estuaries are very productive ecosystems because they receive fresh nutrients from

• lakes and ponds

• rivers and oceans

• marshes and swamps

• streams and springs

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
