Ascientist is studying a population of sharks and pacific ocean. the scientist reports that compared to a few years ago, the sharks are spending less time in equatorial waters and more time in water is in a california and alaska. which statement describes the type of change that is a occurring to the shark population? a. there geographic range is changing. b. deer population density is changing. c. population distribution is changing. d.there carrying space is changing.

The correct option is C. Population distribution is changing.

Explanation:

Population distribution can be described as the spreading of species of a kind on different geographical locations. The population distribution of an area tends to change with changing resources and environmental conditions.

The population distribution of sharks was more in the equatorial waters a few years ago. But due to certain circumstances, the population distribution is becoming more in the waters of California and Alaska now. This might be due to more favourable conditions in the California and Alaska waters now.
