Question

Which type of exile environment is a saltwater fish? Best adapted. 1. isotonic environment 2. hypertonic. Environment 3. hypotonic environment. 4. Osmotic environment

Answer 1

Saltwater fish are best adapted to a **hypertonic environment**. In a hypertonic environment, the concentration of solutes (such as salts) outside the fish is higher than the concentration inside the fish's body. As a result, saltwater fish constantly lose water to the surrounding environment and must actively drink seawater and excrete the excess salts through specialized cells in their gills and kidneys to maintain osmotic balance.
