Do Fish Drink Water?

The video explains how different fish species manage water and salt balance in their bodies. Freshwater fish have a higher salt concentration in their bodies than in their environment, allowing water to flow in naturally. They use chloride cells to regulate salt intake. Saltwater fish face the opposite challenge, as the surrounding water is saltier than their bodies. They drink water and use chloride cells and kidneys to expel excess salt. The video highlights the importance of osmosis and chloride cells in maintaining homeostasis in fish.

Why do some fish need to drink water while others do not?

• All fish drink water regardless of their environment.

• Fish do not need to drink water because they live in it.

• Only saltwater fish need to drink water.

• It depends on the type of fish and their surrounding environment.

How do freshwater fish primarily absorb water?

• Through their skin

• By drinking it

• Through their gills

• By eating food

What role do chloride cells play in freshwater fish?

• They help fish swim faster.

• They regulate the flow of dissolved salts into the fish's bloodstream.

• They pump water out of the fish's body.

• They help fish breathe underwater.

Why do saltwater fish need to drink a lot of water?

• Because they are always thirsty

• To replace water lost due to the high salt concentration outside their bodies

• To help them swim faster

• To keep their skin moist

How do saltwater fish manage the excess salt they ingest?

• They excrete it through their skin.

• They convert it into energy.

• They store it in their scales.

• Their kidneys and chloride cells filter and pump it out.
