Question

9. Which of the following is a primary consumer in the Newfoundland oceanic ecosystem? A) Shearwaters B) Penguins C) Capelin D) Humpback Whales E) Killer Whales
10. What type of zooplankton is most abundant in the southern ocean upwelling zone off of Antarctica?

11. Why is there so much more productivity in the southern ocean upwelling zone during the month of January compared to the month of July?

Answer 1

Answer:

9.) Humpback Whales

10.) Phytoplankton.

11.) Sotronger upwelling winds

Explanation:

9.) A primary consumer feeds on primary producers, of all the options given Humpback Whales, are the only ones meeting the criteria in the options given since they feed with plankton (a primary producer).

10.) Phytoplankton are the base of the Southern Antarctic Ocean trophic chain. In the nutrient-rich upwelling zone waters, they can reach huge blossoms and are far more common than other forms of zooplankton in this zone.

11.) The productivity of this ecosystem is influenced by the seasonal cycle of the upwelling winds, these peak during the months of December and January, carrying more nutrients and allowing trophic networks to work more efficiently and actively allowing for more productivity.
