Question

Which aquatic ecosystems are composed of salt water? Check all that apply.
A. intertidal zones
B. neritic zones
C. open ocean
D. streams
E. coral reefs

Answer 1

Answer:

Aquatic ecosystems that are composed of salt water are coral reefs, open ocean, and intertidal zones. Neritic zones also have salt water, but the salinity levels are very light. :)

Answer 2

Answer:

The correct answer will be options-A, C and E

Explanation:

The amount of dissolved salt present in the water is calculated in the terms of the practical salinity unit or PSU or ppt.

The salinity of the inter-tidal zone lies between 20-25 ppt whereas the salinity of the ocean lies between the 33-35 ppt. The salinity of the coral reefs lies between the 30-40 ppt.

The stream is the freshwater source which contains very less amount of salt and the neritic zone is the zone of the ocean in which sunlight can easily reach which contains low salt concentration.

Thus, the selected options are the correct answer.
