Answer:
The correct option is C) Experience a population decline
Step-by-step explanation:
The population of Otters will remain stable if the population of the preys i.e shellfish and crustaceans, remains stable in an ecosystem. If the population of shellfish and crustaceans begins to decline in an ecosystem, then there will be competition for food among the Otters and other organisms which feed on shellfish and crustaceans. As a result, the population of the Otters will also start to decline due to lack of food.
