Chapter 52: Problem 10

In which habitat must organisms adjust regularly to changing salinity? a. salt marsh b. coral reef c. benthic province d. estuary e. riffle

Short Answer

Expert verified
d. Estuary

Step by step solution

01

Understanding Habitats

Discuss the general classifications of each habitat. - Salt marshes typically occur along coastlines in temperate climates.- Coral reefs are established in clear, tropical oceans and are well-known for their high biodiversity.- The Benthic province refers to the bottom layers of marine ecosystems that includes the sediment surface and sub-surface layers.- Estuaries are partly enclosed coastal bodies of water where freshwater from rivers meets and mixes with saltwater from the ocean. - Riffles are shallow landforms in flowing channels.
02

Salinity Characteristics of Habitats

Discuss the characteristics of each habitat in terms of salinity. - Salt marshes and coral reefs typically have a consistent level of salinity as they are influenced primarily by the sea and less by freshwater sources. - The Benthic province, being part of the deep ocean floor, has consistent high salinity due to the stable sea environment.- Riffles are formed in freshwater environments such as rivers and streams, therefore they don't experience changes in salinity.- Estuaries, being where rivers meet the sea, encounter a continous mixing of fresh and salt water, causing frequent changes in salinity.
03

Selecting the Correct Answer

From the discussed salinity characteristic of each habitat, the estuary is the one where organisms must adjust regularly to changing salinity.
