The election committee that you are chairing finally seems to be getting something done. for a while, you thought nothing would be accomplished; it seemed that committee members were more interested in whose ideas were addressed rather than the quality of the ideas. people have now started to "come together" and are establishing some patterns of interaction that seem productive. the members appear to have worked through the stage and entered the stage of group development.

ans.

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.'
