Otters have adaptive traits that allow them to survive by eating shellfish and crustaceans, the otters will most likely:

The correct option is C) Experience a population decline

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.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
