Question 1: What role do sea otters play in coastal ecosystems?
A They act as predators of kelp forests.
B They help control sea urchin populations.
C They are top predators of fish.
Sea otters feed on sea urchins, which can devastate kelp forests when their populations are unchecked. By maintaining a balanced sea urchin population, sea otters play a crucial role in the health of coastal ecosystems.
Correct Answer: They help control sea urchin populations.
Question 2: What unique behaviour do sea otters exhibit while floating?
A They build nests onshore.
B They hold paws to stay connected.
C They engage in group hunting.
Sea otters are often seen floating in groups, or ‘rafts,’ where they hold paws to prevent drifting apart. This behaviour not only strengthens social bonds but also provides safety from predators.
Correct Answer: They hold paws to stay connected.
Question 3: What danger do sea otters face that can affect their survival?
A Competition from dolphins.
B Oil spills in their habitat.
C Excessive sunlight exposure.
Oil spills are particularly harmful to sea otters since their fur is not waterproof. Oil can damage their insulation, making it difficult for them to maintain body heat, which poses a serious threat to their survival.
Correct Answer: Oil spills in their habitat.
