Where are coral reefs found?

• Polar waters

• temperate, mid-latitude waters

• tropical waters

• only near volcanos

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

• 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
