Grizzly Bears and Salmon: A Nutritional Journey

The video explores the relationship between salmon spawning and grizzly bears' feeding habits. As salmon return to spawn, bears take advantage of this abundance, entering a state called hyperphagia, allowing them to eat continuously. They selectively consume the most energy-rich parts of the salmon. The video also highlights the challenges bears face in catching salmon as they move upstream, and the strategies they employ to maximize their catch.

What is the primary reason bears are first in line during the salmon spawning season?

• They are attracted by the sound of water.

• They are naturally faster than other animals.

• They have a strategic position for catching salmon.

• They are the only predators in the area.

What physiological change allows grizzly bears to eat continuously during the salmon season?

• Metamorphosis

• Hyperphagia

• Photosynthesis

• Hibernation

How many calories can grizzly bears consume in a single day during hyperphagia?

• 10,000 calories

• 50,000 calories

• 200,000 calories

• 100,000 calories

Which parts of the salmon do bears prefer to eat for maximum energy?

• The fat, eggs, skin, and brain

• The bones and scales

• The fins and tail

• The gills and eyes

What makes it easier for bears to catch salmon as they move upstream?

• The water becomes shallower.

• The river narrows.

• The salmon become slower.

• The bears become faster.
