Fish Behavior and Temperature Effects

The video tutorial demonstrates an experiment to observe how fish behavior changes with water temperature. Initially, the fish is in cold water at 50°, showing minimal movement and slow breathing. As the water is gradually heated to 80°, the fish becomes more active and breathes faster. The experiment concludes with an explanation of ectothermic animals, highlighting how their body temperature and activity levels are influenced by the environment.

What was the initial temperature of the fish's water?

• 30°

• 50°

• 70°

• 80°

How did the fish behave in the cold water?

• Very active

• Moderately active

• Very still

• Aggressive

What was observed about the fish's breathing in cold water?

• Breathing irregularly

• Breathing fast

• Breathing slow

• Not breathing

To what temperature was the water heated?

• 80°

• 70°

• 90°

• 60°

What change was observed in the fish's behavior after heating the water?

• Became aggressive

• Stopped breathing

• Started swimming around

• Became still

How did the fish's breathing change after the water was heated?

• Slowed down

• Became faster

• Stopped

• Remained the same

What term describes the type of body temperature regulation observed in the fish?

• Ectothermic

• Poikilothermic

• Homeothermic

• Endothermic

What conclusion can be drawn about the fish's activity level in relation to water temperature?

• Activity is random

• Activity is unaffected by temperature

• Activity decreases with higher temperatures

• Activity increases with higher temperatures
