Explanation:

Frictional unemployment is one component of what economists call natural unemployment, which is unemployment caused by things other than an underperforming economy. Frictional unemployment is caused because of temporary changes in jobs. It involves cases such as new employees entering the workforce, people moving to another city and looking for a job or people leaving to seek a better one.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
