which statement describes the type of change that is occurring to the shark population?
a their geographic range is changing.
b. their population density is changing.
c. their population distribution is changing.
d. their carrying capacity is changing.

Explanation:

The sharks are changing the areas of water they inhabit. Geographic range refers to the entire area where a species is found, but here we are focused on the shift within the Pacific Ocean. Population density is about the number of individuals per unit area. Carrying capacity is the maximum number of individuals an environment can support. Population distribution is about how individuals are spread out in an area, and the sharks are changing their spread - from equatorial to waters near California and Alaska.

Answer:

C. Their population distribution is changing
