Answer 2

http://oceanservice.noaa.gov/facts/estuarylife.html
That website shows animals and plants that live in estuaries.
So i would say C. coral reefs.

Answer 3

C. Coral Reefs ( Most likely )

Answer 4

Whales are normally not found in estuaries (except for one very rare Fin whale in '01) and occasionally Beluga's. For this question however, whales would not be the answer.

Many plant and animal species thrive in estuaries. The calm waters provide a safe area for small fish, shellfish, migrating birds and shore animals. The waters are rich in nutrients such as plankton and bacteria. Decomposing plant matter, called detritus, provides food for many species. Destroying the estuary creates the conditions for flooding. Estuaries provide a natural barrier to ocean waves, which can erode the shoreline and destroy coastal homes and businesses.

With the use of this information, I would also agree and say CORAL REEFS would disappear first.
