Grizzly Bears and Their Ecosystem

The video explores the ecological role of grizzly bears, focusing on their diet, adaptation, and habitat. It highlights the importance of understanding their foraging behavior and the use of satellite technology to map habitats. The video also discusses conservation efforts and the impact of climate change on grizzly bears and their ecosystems.

What role do grizzly bears play in ecosystems?

• They have no significant role.

• They are the top predators.

• They are critical for ecosystem function.

• They are primary producers.

Why do grizzly bears have large claws?

• For defense against predators.

• For digging up roots.

• For hunting large prey.

• For climbing trees.

What percentage of a grizzly bear's diet can be vegetation?

• Up to 70%

• Up to 50%

• Up to 30%

• Up to 90%

How do grizzly bears survive the winter months?

• They rely on stored food.

• They hibernate.

• They become carnivorous.

• They migrate to warmer areas.

What is a key strategy for grizzly bears to gain weight during summer?

• Following plant growth schedules.

• Eating continuously without rest.

• Storing food underground.

• Hunting large animals.

How do NASA satellites assist in grizzly bear conservation?

• By providing real-time images of bears.

• By predicting weather patterns.

• By monitoring plant growth through spectral signatures.

• By tracking bear movements directly.

What is the purpose of dynamic habitat maps?

• To show static images of bear habitats.

• To calculate the carrying capacity of habitats.

• To track bear population numbers.

• To identify bear predators.

How can habitat maps help during important feeding periods?

• By predicting bear migration routes.

• By indicating areas to avoid disturbing bears.

• By showing where bears are not present.

• By highlighting areas with no food.

What impact does climate change have on grizzly bears?

• It has no impact on them.

• It disrupts their foraging schedule.

• It stabilizes their foraging schedule.

• It increases their food supply.

How do habitat maps contribute to understanding ecosystems?

• By showing only grizzly bear habitats.

• By highlighting areas with no vegetation.

• By focusing solely on plant species.

• By aiding in understanding ecosystem functions and threats.
