Zooplankton are an important part of almost all marine food webs. In which part of the water column are zooplankton most abundant?
- A.

- D.
  
  Epipelagic- the sunny surface
Correct Answer
D. Epipelagic- the sunny surface

Explanation
Zooplankton are most abundant in the epipelagic zone, which is the sunny surface of the water column. This is because sunlight penetrates this zone, allowing for photosynthesis to occur and providing a source of food for zooplankton. Additionally, the epipelagic zone is also rich in nutrients, which further supports the growth and abundance of zooplankton.

  Sea otters
- C.
  
  Fur seals
- D.
  
  Sea lions
Correct Answer
A. Polar bears

Explanation
Polar bears have the thickest coat of fur among these marine mammals. This is because they live in extremely cold environments, such as the Arctic, where they need a thick layer of insulation to keep warm. Their fur is made up of two layers: a dense undercoat and longer guard hairs. This combination helps to trap air and provide excellent insulation, keeping the polar bears warm even in freezing temperatures.

Rate this question:
9.

Which of these marine animals is NOT a jellyfish?
- A.
  
  Sea nettle
- B.
  
  Comb jelly
- C.
  
  Sea wasp
- D.
  
  Portuguese man o'war
Correct Answer
B. Comb jelly

Explanation
A comb jelly is not a jellyfish because it belongs to a different phylum called Ctenophora, while jellyfish belong to the phylum Cnidaria. Although both comb jellies and jellyfish are gelatinous marine animals, they have distinct differences in their anatomy and behavior. Comb jellies possess rows of cilia that they use for locomotion, while jellyfish have tentacles with stinging cells called nematocysts. Additionally, comb jellies do not have a centralized nervous system like jellyfish do. Therefore, the comb jelly is the correct answer as it is not classified as a jellyfish.
