Question

Accepted Answer

Step 1 — Definition:

- Freshwater habitats have low dissolved salts; seawater is saline with much higher salt content. In notation: $	ext{salinity}_{	ext{sea}} \gg 	ext{salinity}_{	ext{fresh}}$, so $	ext{sea water} 
eq 	ext{fresh water}$.

Step 2 — Which are freshwater habitats:

- Rivers, creeks, lakes, ponds, and streams are all classic freshwater habitats.

Step 3 — Check each statement:

- (1) "Pond water and sea water are considered as fresh water." — False (pond = freshwater, sea = saline).
- (2) "Sea water is freshwater habitat." — False.
- (3) "Rivers and sea water are considered as fresh water." — False (rivers = freshwater, sea = saline).
- (4) "Rivers, creeks, lakes, ponds, and streams are all freshwater habitats." — True.

Conclusion: Only statement (4) is correct.
