Question

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 please select the best answer from the choices provided?

Answer 1

D. take polar bears, for example, they have a narrow temp. tolerance, they are used to cold weather so when climate change affects the temp. some polar bears will die which will be a cause in decreased population and some may try to change the location to survive.

Answer 2

Answer: d. all of the above

Species living in narrow temperature tolerance range are those species which undergoes very little or no adaptations with respect to the varying temperature conditions. Adaptation is the only factor which can either limit or extend the tolerance level with respect to the wide temperature range. Therefore, species undergoing few or unfavorable adaptations in the narrow temperature tolerance range will result in species population to extinct, decrease in population and species can also change their migratory patterns.
