Question

A five-year review of threats to the southern resident orca population of the United States concluded that the top threats were prey availability, contaminants, and effects from recreational and whale watching vessels. Further down the list are oil spills, disease, and effects from commercial vessels not targeting whales. How might this list be different if it were for transient whale populations, which have a larger average population size and live farther offshore in open waters?

The transient population is more likely to be affected by contaminants.
The transient population is less likely to be affected by whale watching vessels.
The transient population is more likely to be affected by disease.
The transient population is less likely to be affected by prey availability.

This is for study guide. Which one would it be?

Answer 1

The transient population is less likely to be affected by whale watching vessels.

Answer 2

Answer:

The correct answer is the second statement.

Explanation:

The transient populations’ exhibit unique merit of being able to move in between distinct places, and therefore, are less influenced by the detrimental local conditions. Because of the fact that there are more individuals in an average in a population, and the fact that they thrive farther offshore, the influence of whale watching vessels on the entire population is most possible to be the least.  

Due to the fact that the population does not thrive in the similar location for the prolonged-time period, it is less possible to be influenced by the local contaminants, diseases caused by local conditions, as well as the availability of prey.
