Marine Life and Ecosystem Dynamics

The video explores the habitat and behavior of gannets and other marine life around Bonaventure Island. It highlights the feeding habits of gannets and the presence of various marine animals, including the endangered North Atlantic right whale. The video discusses the challenges faced by these whales due to hunting and ship collisions. A significant discovery of multiple whale species in a specific area leads to a theory about localized upwelling, which brings nutrient-rich waters to the surface, attracting marine life. The video concludes with observations on the marine ecosystem's dynamics.

What is the wingspan of a northern Gannet?

• 2.5 meters

• 2 meters

• 1.5 meters

• 1 meter

Which island is known for having the largest northern Gannet colony in North America?

• Bonaventure Island

• Galapagos Island

• Hawaii Island

• Madagascar Island

What is a significant threat to the North Atlantic right whale population?

• Climate change

• Ship collisions

• Overfishing

• Pollution

Why is it difficult to spot North Atlantic right whales?

• They are rare due to hunting

• They only appear at night

• They travel in large groups

• They are very small

What might be attracting various whale species to a specific area?

• Warm water temperatures

• Abundant food sources

• Sheltered bays

• Calm weather conditions

What is the term for the upward motion of water that brings nutrients to the surface?

• Thermocline

• Localized upwelling

• Downwelling

• Tidal surge

What effect does localized upwelling have on marine life?

• Causes water pollution

• Decreases water temperature

• Increases nutrient availability

• Reduces fish populations

What happens when a deep-sea current hits a sudden rise?

• It moves upward

• It flows sideways

• It moves downward

• It stops completely

How does the structure of the harbor affect marine species?

• It only affects birds

• It determines the species found there

• It has no effect

• It only affects fish

What is the significance of the navigational aspects mentioned in the video?

• They determine species distribution

• They are irrelevant to marine life

• They help in fishing

• They guide ships safely
