Final answer:
A species that cannot tolerate a wide range of temperatures will have greater cold tolerance where it is colder. It is adapted to specific conditions and differs from an 'isolated system' in physics.
Step-by-step explanation:
A species that cannot tolerate a wide ambient temperature range is likely to have greater cold tolerance in the colder parts of its range than in the warmer parts. These organisms are adapted to their local climate and may struggle to survive if conditions change or if they are moved to an area with a different temperature profile. This concept is not related to the term 'isolated system,' which is a system that does not allow a transfer of energy or matter into or out of the system, commonly discussed in physics and engineering.
