Question

select the correct answer from each drop - down menu. fish that can survive saline and freshwater environments can be found in

are ecosystems found in warm, shallow portions of the ocean.

Explanation:

To solve this, we analyze the ecological context:

1. For the first blank (habitat of euryhaline fish): Fish that survive in both saline (ocean) and freshwater are euryhaline, and estuaries are where freshwater (rivers) meets saltwater (ocean), making them ideal for such fish.
2. For the second blank (shallow, warm ocean ecosystems): Coral reefs are warm, shallow marine ecosystems with high biodiversity, matching the description.

Answer:

First drop - down: estuaries
Second drop - down: coral reefs
