The interdependence principle: is the same as the cost-benefit principle. implies that consumers depend on each other to make purchase decisions in the market. implies that buyers decisions are affected by many factors other than the price of an item. refers to the marginal benefit of consuming additional units of an item.

Option a (impliesmarket) is the right response.

Explanation:

Some other options available are not connected to the circumstance in question. So the option above is correct.

i would have to say its c

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.'
