What is a possible consequence of climate change to species that have a narrow temperature tolerance range? a. extinction b. decreased population c. changes in migratory patterns d. all of the above

a. extinction

Explanation:

The species that have a very narrow temperature tolerance are usually species that are very specialized for their environment. These species are the ones that suffer the most if there's changes in the environment, and usually are the first ones to go extinct. If the temperature changes, especially if it happens relatively quickly, apart from the difficulty that species will have with the temperature itself, it will also have huge problems with the quickly changing habitat. The end result will be a quick demise and extinction of the species.
