Fish that can survive saline and freshwater environments can be found in . are ecosystems found in warm, shallow portions of the ocean.

Answer 1

Please find the answer below:

(i) Fish that can survive saline and freshwater environments can be found in estuaries. 

Estuaries have varying levels of salinity which depends on tide, season, and weather.

(ii) Coral Reefs are ecosystems found in warm, shallow portions of the ocean.

These are forests underwater that are a habitat to several types of fish. Hence, they survive in warm shallow waters.

Answer 2

The reason some fish ordinarily live in freshwater and others live in seawater is that either condition furnishes them with circumstances that have generally added to their survival.

A conspicuous contrast between the two living spaces is salt focus. Fish that live in the two situations hold the two components.
